Made with Fusion 360. A toy car with double-acting 1-cylinder compressed air engine (like the steam locomotives have). Has steering, which even works. I call it "vapemobile" because of the remote shape).

Apart from these printed parts, you'll need some extra ones to assemble it:

* 623ZZ bearing (4x10mm, 3mm hole) (may poorly work without it)
* Piece of 1.75mm filament
* Rubber band
* Thin plastic bag
* 6mm silicon pipe (can be found in any aquarium shop)
* 4mm pipe from intravenous dropper (or any that you could pull onto the syringe end)
* Two 2ml syringes

Simple Wall panel that I made to test out some emission mapping and more procedural stuff. 
Free to use in games or VR chat.

UV'ed correctly all you need to do is place the textures correctly in Unity or Unreal.

For this model, I researched various types of generic pirate treasure chests. I combined common elements such as rusty bolts and metal detail on the edges the maximise the chests surface area efficiently. I chose to angle the base of the chest inwards to make it more distinct and recognisable along side other generic box chests. 

To save time, I chose to create the internal jewellery using a texture map. The diffuse map was prcoessed through Materialize to provide Height and Normal maps which were then brought over to Substance Painter. For the wood texture, I chose a more muted tone to help enhance the stark brightness of the gold. Height layers were used to create a plank like effetc on the wood.

Ablasstruhe / Indulgence Chest

This is a Crossbow that i modelled in Maya and Textured in Substance Painter. This model took around 10 hours to complete and another 4 hours to Unwrap. The design of the Crossbow is based on the old Medievil Times but i decided to give it a more modern day look to it. The overall poly count in maya was 5k but Substance Doubles it when texturing.

A crossbow is a type of weapon based on the bow and consisting of a horizontal bow-like assembly mounted on a stock. It shoots projectiles called bolts or quarrels. The medieval crossbow was called by many names, most of which were derived from the word ballista, a torsion siege engine resembling a crossbow.

Told of in Oriental legends, it is the strongest destructive god and the god which governs over regeneration. It is told that when the Network System descends into chaos, it will erase the existing system, and create a new one. Its Special Moves are slicing and stabbing everything in the world with the sword of light emanated from the "ZERO-ARMS: Orochi" (Ama-no-Habakiri), and an ultimate technique in which it points the sword of light (emanated from the ZERO-ARMS: Orochi) at the heavens, which then rain incessant bolts of lightning upon the ground (Yakusa-no-Ikadzuchi).

# **Urban Electrical Box**
**Graffiti & Decay**

*A worn street electrical box covered in layered graffiti, stickers and urban grime.*

The surface shows years of exposure to weather and city life — rust streaks, dirt buildup and faded paint create a believable sense of age. 

**Various graffiti tags** and an **anarchy symbol** add to the raw street aesthetic, while scattered stickers and scratches give the object **character and storytelling** detail.

Small details like vent slots, bolts, subtle dents and accumulated dirt help sell the realism. The base shows heavier rust and grime where water and debris naturally collect. The asset also includes nearby discarded bottles to enhance the environmental storytelling.

Perfect for urban environments, street scenes, abandoned areas, **cyberpunk** settings or **post-apocalyptic worlds.**


# **Features**

• Realistic urban prop

• Detailed graffiti and sticker decals

• Rust, dirt and weathering

• Game-ready asset

• Suitable for real-time environments

Old Wooden Barrel With Metal Fittings

Deep in a forest far away,
Lived a guy a bit “okay…”,
A lumberjack, a handyman,
With very questionable plans!
One day he said, “I’ve had enough,
Walking slow is way too rough!
I’ll build myself without delay
A crazy ride to save the day!”
He grabbed an old grinder tool,
A rusty frame, some bolts not cool,
A bit of string, a shaky plan…
And way too much confidence, man!
 Vroom vroom, buzz buzz!
Hear that noisy fuzz!
Cuts down trees while flying by,
Makes the whole forest wonder why! 
 Vroom vroom, buzz buzz!
Watch out little pines!
When he starts that crazy ride,
Even squirrels run for their lives! 
He speeds between the trees so fast,
Wood chips flying as he blasts,
A twist of throttle, loud and proud—
And poof! no tree… he laughs out loud!
Deer just stare as he goes past,
Owls look shocked by how he blasts,
And him, so proud, king of the wood,
Laughing like he really should!
“They say it’s unsafe,” folks complain,
“That thing is driving us insane!”

-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.
