This model is a mount for a Diamond or Bowtech compound bow to mount a GoPro or similar small action camera to the bow riser in one of several proprietary recesses machined into the riser (the rounded-corner triangle in this case). The model is made in two parts - the mount itself which can be customized for other model bows (some have hexagons, some have other shapes), essentially providing a mount that will not pitch (tilt up and down) with use, vibration or anything else that might jar the camera and leave it pointing in the wrong direction at the moment of truth.
Increasingly these days archers are video-capturing their target, whether it is a competition target or an animal hunted for food. Using Prusa Slicer I was able to insert a “Pause SD Print” which on my Marlin based firmware is an M25 code to park the nozzle so that a nut can be inserted into the post before it is resumed, filling extruded plastic over the nut and effectively embedding it in so that a real metal fastener can be used to secure it in the bow. Unfortunately uploading the GCODE file with this pause in it was disallowed because “unknown M25 code - the file may be corrupt” error and wouldn't upload the file, presumably because it is a different flavor of GCODE (RepRap), than that used by Prusa printers.
The pause is meant to be inserted at Z=34.95mm, which is easy to do with Prusa Slicer and there are many examples of this on the Prusa Slicer help and YouTube videos. Once the ¼-20 nut is set into place printing resumes and when the Riser Attachment post is printed it will allow a corresponding ¼-20 x 2" bolt to be inserted through the riser and the camera platform secured into place. Additionally there is a counterbore and nut pocket for an M5x0.8 x 25mm bolt and nut which is used to lock the Camera Platform to the Riser Attachment with some room for left/right adjustment.
If your bow is fitted with a side-rod stabilizer the yaw of the stabilizer can be adjusted to re-balance the bow (roll axis) to account for the mass of the camera. Printed in Hatchbox PLA Pro+ at resolution of 0.2 with a 0.4 mm nozzle.
