ArChery Cam Print All at Once - no assembly needed

thingiverse

Update: Instead of 3D printed riser I decided to use the PVC pipe, like you can see on one of the pictures. To lighten and stabilize the cam I've put all the parts together. Print with support as necessary, no assembly needed afterwards. Due to lack of metal screws the design is lighter and more stable. Adjust fill % and wall thickness when printing to get the desired strength and weight. I printed with 25%, 0.8mm wall. My 20x20 print area allowed for only 0.85 scale of original size. This is work in progress. I might add axles to get rid of bearings and support the cams on wider pivot base for stability. Modified brackets to accommodate DN25 PVC pressure pipe. Outside diameter of the pipe before flattening: 33.5mm.

If that is your case just heat one side of the affected arm of the bow and twist it until parallel. It will be well visible on the "string". Let is set by cooling down. Voila! Tension the strings and cut the ends with hot soldering iron and tie when everything aligns well. For the "bearings" of the cams I just 3D printed small barrel like washers fitting sides of the cam or use real bearings. Use it on your own responsibility. The author doesn't guarantee it to be fit for any purpose whatsoever.
