This is the sled of most sights on the guest bows in our archery club. When handled roughly by the guests these things sometimes break on the bottom clamp part. I'm trying to recycle the metal parts of this thing (especially the metal threaded bushing for the clamping action) by removing everything from a broken sled and inserting it with some heat into a newly printed one. This is a work in progress, once I get my 3D printer working I'll iterate over this to improve the stability of the original Design, probably by giving it a more sturdy clamping section. The picture of the orange one is the original part that I'm trying to replace.
