⚠️ This is now an old design. A fully parametric arm design is now available and is the recommended version — Parametric Universal Boom Arm. This new version is easier to remix, uses less filament, and was built with a slightly increased knowledge of CAD :D.

This is a desk clamp microphone arm stand with 3 degrees of freedom that has been fitted with a swappable microphone screw attachment and desk clamp. The mic screw are attached via screw holes and can be modified to what ever you want if you can design it :).

The mic screw is attached to the mic arm with a 3D printed M8x1.25 thread that then turns into a custom made Logitech mic screw.

I printed this arm with a P1S:

Nozzle size: 0.6mm

Wall layers: 3, (recommended high wall count especially for the mic screw)

Supports: only used on the bolts as they we printed horizontally (avoids layer line failures)

infill: adaptive cubic 15%

Rough print time: 6.5hrs

Total filament used: 332g

Note: The nuts in the .mf3 file have been scaled to 110% and the clamp bolt and clamp head were scaled to 98% and 96% respectively as this lead to a better fit for me. If using the STLs some scaling may be required to the previously listed parts.
