Butrón (Basque: Butroeko gaztelua) is a castle located in Gatika, in the province of Biscay, in northern Spain. It dates originally from the Middle Ages, although it owes its present appearance to an almost complete rebuilding begun by Francisco de Cubas (also known as Marqués de Cubas) in 1878. The castle has a fairy-tale look about it inspired by Bavarian castle models. The present building was created as a hobby for its then owner and to create something which is visually spectacular rather than to produce something in which people could actually live. In fact it would be quite inconvenient as a home as the towers have little useful space and various parts of the castle have exterior connections which are not particularly apt for the wet Basque weather.  https://en.wikipedia.org/wiki/Butr%C3%B3n

Modular City Road Pack – Game Ready

The team from the Museum's boatbuilding school have recently completed two skiffs as a joint project with Garnock Connections and Rathbone Training. 

Here you can have a closer look at the process behind the making of these skiffs. Their hulls are based on a traditional vessel: a Fair Isle Skiff, the model of which can be found in the  Scottish Fisheries Museum. It was constructed as a demonstration project in 2009 and started a true revival of the coastal rowing in Scotland. 

The original design of the skiff was modernised enabling anyone without a boatbuilding experience to take on a similar project with a bit of guidance from the experienced boatbuilders. Today people from all over the world build similar skiffs and regularly attend championships. 

Listen to Martin, the School Manager explaining how these vessels are made.

The German 35.5cm M1 Super Heavy Howitzer only 6 made in existance ( from what I researched ), with very little reference I managed to completly replicate the model using blender and rendered inside of Unreal Engine 5 on my artstation portfolio. This did not take long to make, and is completly optimised to be used in game engines, however I would prefer to use ORM packed maps for the textures but they are all individual for Sketchfab purposes. I have animated and rigged this model which ou can see a short preview.

I am completly open to asset comissions and job opportunities and would love for any, just message more or email through my artstation account. I know I don't have many props on my sketchfab but this is just becuase I barely upload on here to be honest. if you download and love this asset please follow me on artstation and linkedin, as I love more connections and giving feedback on any work :)

This 3D model represents a clevis mounting bracket with a cylindrical housing, designed as part of a mechanical CAD practice series. The component includes a hollow cylindrical body supported by a base plate with mounting holes and a dual-ear clevis feature for pin or pivot connections.

The design demonstrates common mechanical CAD techniques including extrusion, hole features, cylindrical geometry creation, and feature-based modeling. Such components are commonly used in mechanical linkages, hinge mechanisms, and structural mounting assemblies.

This model was created to practice parametric solid modeling and mechanical component design.

This object is a computational reconstruction of the classical Klein bottle, a non-orientable surface where inside and outside become indistinguishable.

The model is built from a high-resolution parametric domain (256 × 128), generating 32,768 vertices and over 230k total edges, including 166k structural edges.
Multiple edge families — bands, braids, bridges, and seam connections — reveal the internal organization of the surface and make the topology visually readable.

A spectral encoding system maps intrinsic geometric channels (seam proximity, twist, braid energy, and latitude phase) into vertex color and scale, transforming the surface into an informational object rather than a purely aesthetic form.

Because a true Klein bottle cannot embed in 3D space without intersection, the object is shown as an immersed surface in ℝ³, where self-contacts naturally emerge from the topology itself.

Sunflower Phyllotaxis Ultra is a biomorphic “flux geometry” built from Vogel’s phyllotaxis model (optimal seed packing). 

Seed centers follow the golden-angle spiral: θ = n·137.508° (= 360°/φ²) and r = c√n, then lifted onto a 3D parabolic bowl z = 0.015 r². 

Each of the 1,200 seeds is connected to its 6 nearest neighbors (KDTree), but connections are not simple lines: every link is a volumetric Flux Tube composed of 6 twisted strands (twist rate 8) to create cable-like density. 

Fibonacci spiral families become visible (21/34/55 …) as emergent structure. 

This is a line-based OBJ (l primitives) with embedded vertex colors (emerald→cyan→gold index gradient), generated entirely by mathematics—no hand modeling. But i played with the hue for effect on this site.

Stats: 526,050 vertices / 505,008 edges, file ~31.5 MB.

**K3 Quartic CY2 Flux** is a computational 3D interpretation of the quartic K3 surface, defined by (x₀⁴ + x₁⁴ + x₂⁴ + x₃⁴ = 0) in (CP³). 
K3 surfaces are among the most important compact complex surfaces in modern geometry and mathematical physics, with Hodge numbers (h^{1,1}=20) and (h^{2,0}=1), and deep connections to lattice theory, dualities, and string compactification. 
This model translates that higher-dimensional structure into a readable flux-based object using the PAPP protocol: multi-strand tubular geometry, projected spatial organization, and sculptural connectivity. The result is not a literal embedding of the original manifold, but a computational artifact designed to evoke the internal symmetry, compactness, and mathematical richness of the K3 geometry through a 3D expressive form.

-A brief, anecdotal reminder-
The 'Topox' case includes:
-HP41 CX + memory expansion modules
-HPIL loop for controlling the following accessories:
-a digital cassette player
-a thermal printer
-Topocom software (real-time data entry and calculations, management of point files addressable by point numbers)
-a charging unit for recharging all peripherals with LED charge indicator -a removable lid.
-HP41 CX + memory expansion modules
-HPIL loop for recharging all peripherals with LED charge indicator
-a removable lid The system was operational as early as 1983 using a ZEISS Elta46 device.

Note: Later, the Topocom software evolved (Topo6tem) to control servo motor stations such as the SM540, 640, and 5601.
This system was then installed on an HP IPAQ Business Navigator and used Bluetooth connections for complete machine control.
Thanks to this system, my wife and I could respond to our clients' requests in real time.

-The minimum required for the ATX tray are models Core and IO to hold the motherboard and pci cards (6 motherboard screws, or with the extensions, 9 motherboard screws).-8 total models snap-fitted and then secured with a total of 25 size M3x12mm( or similar) nuts and bolts (phillips head recommended).-Optional stand for using the tray in upright position. The motherboard and pci cards can be directly screwed onto the tray stands/holes with generic motherboard screws. The best print-result for me was to print without changing orientation and using a 0.4mm nozzle for the snap-fitting connections.The taller models have 1mm horizontal support beams to be used with tree supports and are to be cut away.-Models are max 18.2cm in length I suggest cutting out one of the pci-slot beams if its in the way of inserting a thick hmdi plug. 02-27-2026 - added 3 extra screwholes on the extensions to actually make the model ATX.02-26-2026 - v1.1 updated the models, added an optional stand.02-25-2026 - corrected io-shield height and added extra holes for nuts/bolts to the extension parts.

**Complete Intersection CY Flux** is a computational 3D object inspired by complete intersection Calabi–Yau manifolds, one of the major families of Calabi–Yau threefolds studied in algebraic geometry and string theory. 
In the collection notes, this piece refers to the complete intersection perspective in projective space, linked to the broader CICY landscape cataloguing thousands of distinct examples with varied Hodge data. 
Through the PAPP methodology, this higher-dimensional class is reinterpreted as a flux-based 3D artifact built from bundled tubular structures and projected connections. 
The result emphasizes multiplicity, constraint, and constructive intersection, giving visual form to the idea of a manifold defined not by a single equation but by the simultaneous meeting of several geometric conditions.

The brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. The brain is made up of many specialized areas that work together: • The cortex is the outermost layer of brain cells.

**Orbifold CY Z5 Flux** is a computational 3D interpretation of an orbifold-style Calabi–Yau construction obtained by quotienting a toroidal space by a discrete symmetry. 
In the collection notes, this object is associated with an orbifold (T⁶/ℤ₅), where singular points emerge from the quotient structure and can be resolved into smoother geometries. 
Within the PAPP framework, those higher-dimensional ideas are reimagined as a flux object built from multi-strand tubular connections, emphasizing symmetry, folding, and concentrated singular structure. 
The piece is best read as a sculptural translation of quotient geometry: a compact form where discrete symmetry, singular behavior, and resolution logic are condensed into a single 3D artifact.

Flower of Life Flux Complexity is a computational 3D wire-structure built as a dense spatial lattice inspired by Flower of Life logic and translated into a volumetric flux graph. 
Rather than a closed surface mesh, the object is a single connected network composed of 863 vertices and 4,452 structural line segments distributed across a symmetric 12 × 12 × 12 spatial field. 
All connections are uniform in length, giving the piece a highly regular internal rhythm despite its visual complexity. 
The result reads as a sacred-geometric complexity field: part lattice, part energetic scaffold, part mathematical diagram extruded into space. Instead of representing a single solid body, this object reveals structure through connectivity, repetition, and spatial resonance, turning Flower of Life pattern logic into a coherent 3D computational artifact.

Shamseh Glome v4 is a 4D-informed graph object generated through the PAPP protocol. 

The model preserves the original Shamseh V4 structure of 24 constant-colatitude shells, Fibonacci / golden-angle point placement, spiral intra-shell connections, and nearest-shell 4D flux edges, replacing the previous linear radial law with a true S³ latitude law.

The exported geometry is the orthographic xyz projection of the glome, where each shell radius follows r_xyz = R sin(θ) and the hidden fourth coordinate follows w = R cos(θ). 

Symmetric shells above and below the equator therefore share the same projected xyz radius while carrying opposite w values, encoded in vertex color. 

The shell populations follow a sin²(θ) distribution, consistent with the exact latitude weighting on S³ (R² = 0.999992).

The result is a discretized 3D graph representation of genuine glome latitude structure — not a conventional 3D sphere — with 110,480 vertices, 728,359 edges, and the hidden 4th dimension explicitly preserved and visible.
