This is a mounting arm for the Z-axis of a Snapmaker 2.0. Two lengths. Each length allows mounting a webcam; I think the longer arm gets a better angle on the print.

The Z-axis arm can be used to mount anything else - feel free to make new mounting arms! There is a cutout for a 3.5mm cable in the x-axis arm for cable organization. The small piece printing out in the middle is to seal that up (see pics).

I had a logitech C910 webcam laying around (remember when we used to buy webcams separate from laptops?) so I took it off it's mount and attached it to the mounting arm.

I used 2 M3 x 25mm screws, though you could probably get away with 20 mm. There are recesses for lock nuts or standard nuts; your call.

I printed in ABS with a 20-line brim for adhesion on the long arm. I'm guessing PLA won't need a brim, but I have an enclosure and wanted the long-term heat tolerance.

I used supports because of the overhangs in the cable management part of the Z-axis arm, but I'm sure you could slice it so that wasn't necessary.

Route the cable back while attaching the camera arm, then the cable can go through the channel in the z-axis arm.

I had to ream out the M4 holes a bit just at the top where the piece was against the print bed. I may have had my Z too low in an effort to get more adhesion.

After cleaning out the supports and the brim it went together just fine!
