Multi-Purpose Modular Arm

Fully modular and highly adaptable

The system allows you to mix and match components to fit your specific needs. Print only the parts you require and adjust the configuration as you need.

Expansion

The project is designed to be easily adaptable to individual needs. You can either create a round 30,2mm pocket with 5mm depth and an M8 hole, or adapt the other way around by using a 30mm round extrusion with 5mm height and an M8 hole.

Required Hardware

All parts are designed to connect using M8 nuts and bolts. Some models require additional hardware to mount accessories (eg. cameras). This is mentioned in the file name (eg. m6_camera_mount.stl). Some parts may be pre-threaded for M8 bolts, if mentioned in the file name (eg. desk_clamp_threaded.stl). 

Changelog

This is an ongoing project. If there's interest, I'll create additional adapters and mounting options. I'd love to hear your suggestions in the comments.
