pySpectrometer Mounting Rig

A printable mounting system for the pySpect project.  It can accomodate 15 mm or 25 mm spectrometers and a camera with a M12 lens mount. for use with https://github.com/leswright1977/PySpectrometer2

The Camera mount holder is a press fit onto the M12 mount, between the mount and the lens.  you can purchase them on ebay or amazon.  they normally come in packs of 10, but if you can figure it out, there are printable ones.  I didn't have good results with them, but give it a try.

All hardware for the clamps use M3 hex head machine screws and  ½ height square nuts. I used 8mm length, but that's the minimum length, go longer if you want.

If you use the pi camera or picam2, you will also need M2 screws to attach the camera to an M12 lens adapter. You may need to add washers as shims to adjust the specrum in the camera. Add a bit of blu-tack to the lens threads to prevent accidental adjustment of focus.

I have not tested this with the Raspberry Pi High Quality camera.  it would need a different mount.

The integration sphere glues together.  you can coat the inside with barite if you want (see the github for more information about barium sulfate coatings). Look for a spherical stand if you don't have anything on-hand.

I have not included any stands for the rig, but you can adapt a gopro or other phone mount.

PLA is fine, I used 10 or 15% infill.  More perimeters will make it a bit more rigid.

you will need

3+ M3 machine screws 8mm or longer.  

2+ M3 x 12 mm for the 15 and 25mm top clamps

2+ M2 screws for M12 to pi camera mount. I think I used 10mm?

5+ M3 square thin nuts DIN 562, 1.8mm thick

Press the nuts into the clamps until they line up with the holes.  use a thin screwdriver or punch.
