About this 3D model
Base adaptator : 32mm round to 30mm square. Model created in tinkercad. very simple, not tested. Principe : should have some "on the floor" and other 10mm up", for overlap. Feel free to alter and adapt, that's why there is .obj file. [Edit 2025-11-23 : change licence to BY. you can sold them if you want... was wondering about CC0... so... enjoy ;)]
