Low profile telescope focuser
thingiverse
To use my Canon EOS camera with a small telescope, I designed a shorter focuser body that fits the original tube and gears. An adapter from Thingiverse connects the camera to the focuser tube, fitting perfectly on its 32mm OD (1.25" approx.) but not compatible with standard 1.25" or 2" lens mounts. Print settings include rafts, supports, and a 0.1mm resolution. The OpenSCAD files are parametrisable, though careful parameter checking is needed. I recently printed the cap holding the pinion gear (photo attached). Uploaded cap files too.
