Spar beam mount for 6mm foam, 6x6mm & 12x6mm beams

thingiverse

Mount for "12x6mm" and "6x6mm" balsa/hardwood beams into 6mm or deeper foam surfaces. These are best for removable wings/surfaces rather than a permanent fixture. "12x6" balsa beams are often 12.8x6.6mm or thereabouts in reality. The various sizes should allow a firm fit. You can always scale manually in slicer. If you need a very particular size just ask, I will provide. These are quite strong in my use, but I would not trust them under very high loads. Good for small wings/tails but probably not as the sole attachment for an entire wingspan. Installation - cut small grooves to match the teeth, fill with hot glue or whatever, press firmly in place. These are basically permanent and not easily removed without damaging the foam.
