Hole Savers for Skewer + Foam board

thingiverse

Simple hole savers for foam board + skewer construction. Use in place of chopped up gift cards. I print mine in batches of 9 or 12 with a brim. The brim acts like the framing you find around plastic models. Note: I model knowing the limitations of my 3D printer. Its old and has a few minor quirks. In general its accurate but holes especially tend to print out smaller than they are sized in the model. As such I model holes slightly larger to accommodate this. Test print any part and make sure any attached hardware like wire or skewers fit properly before bulk printing.
