Goniometer Rotate-and-Tilt platform for camera fine adjust

thingiverse

This is a goniometer design i.e. rotate-and-tilt platform. The idea is to attach a camera on top, and be able to accurately orient it for piggy-back astrophotography on a telescope or mount. It only requires an additional metal screw to attach the middle part on the bottom base, avoiding the camera to fall. It is derived from: - https://www.instructables.com/id/3D-Printed-Pan-Tilt-Goniometer/ in a more compact layout, and with 1/4" holes for the camera, markers, and centring. The TinkerCad model is: - https://www.tinkercad.com/things/0qa0Knh0zka-goniometer-pan-n-tilt Print settings ========== **Material**: You can print with PLA and PETG. PETG is supposed to be more sturdy and flexible. So I would recommend PETG for most parts. I chose black for all parts, except pan and tilt screws as light green. **Print settings**: Most parts are printed at 150 or 200 um layer resolution, no raft, no support. Infill 60%. - Bottom: make it flat on the bed. - Top plate: make it flat up-side-down, _with_ support (for the two outer cylinders on the axis). - Middle: I printed it flat _with_ support, to hold the middle plate, and keep the gear with high resolution. You may try something different (i.e vertical), but I guess supports will be needed anyway. - Screws: you need two of these. Print them vertical, _with_ a raft. - Screw holder: you need only one of this. Print it up-side-down. Post-Printing ========== Polish a little the parts, including the two holes in the middle part. The top plate clips in between the two opposite walls of the middle part, while holding the middle pan screw. Then drop the assembly into the bottom part, with the bottom screw on the side. Optionally, hold the bottom rotate screw with its holder that gets in its opposite shape. Use a metal screw to keep the goniometer tight. This will avoid the camera to fall when the mount is inclined.
