No. 66 · Star from a core and 20 spikes – print files
4.75 – 2 pieces of feedback on the shop (not verified)
A three-dimensional star, 120 mm tip to tip: an icosahedron core with 20 plugged-on hollow pyramid spikes. One spike carries the eyelet for hanging.
The core is an icosahedron with 30 mm edge length, split into two half cores that are joined with three dowels. Each of the 20 triangular faces carries a peg with 45° flanks. The spikes are hollow pyramids (37.3 mm high, 1.8 mm wall) with a pocket that is pushed over the peg. The clearance is 0.3 mm at the bottom and 0.12 mm at the top per side.
The spikes stand on their base during printing, the half cores lie with the cut face on the bed. The spikes have a closed cavity inside, which the slicer reports as an interior space. The spikes are pushed onto the pegs without glue (wedge fit).
Print notes included in German; part names are self-explanatory.
