This mount is optimized for Samsung A-series phones, but it can securely clamp many other phones as well. The clamp is designed thicker because it is intended to be used with a phone case. The clamp base STL is recommended to be printed in PETG, as it is the most mechanically stressed 3D-printed part of the assembly. Recommended print settings: Minimum of 3 walls (perimeters) Minimum of 15% infill Hardware required: 8 × 25 mm M3 countersunk screws (to help resist pulling stress between layer lines) 2 × 50 mm M3 countersunk screws (for clamping the phone) 8 × 3.5 mm M3 heat-set inserts 2 × 8 mm M3 heat-set inserts
