Needed a simple pair of anchors to mount a 15mm diameter pole to a shelf, might as well model everything and make them overengineered. If your printer can bridge 7mm of length then it can print these anchors without issues.
BOM
- 2 countersunk wood screws for each anchor. Not sure what the official specification is for them, so I measured relevant features: 2.9mm diameter counting the threads, 11mm length is sufficient but you can go longer if you want. The head is 5.8mm diameter
- superglue to stick the pole in place
Instructions
Mirror the stl to get the other side, don't print two identical pieces
Glue the pole to the anchors to ensure it doesn't slip out if moved, I didn't want to screw it on so there are no screw holes
Features
- print orientation ensures maximum strength
- every overhang maxes at 45 degrees, easily in reach of any printer
- every edge is chamfered, both for nicer looks and to avoid elephant foot on the bottom side
- removed material from the edge touching the shelf to allow for cutting imprecision
- every hole has a flat top to avoid drooping layers
- the only feature that has a bridging section has built-in support that will easily detach afterwards
there are much simpler ways to make such anchors, but where would the fun be in that?
