Parametric 8-way Connecting Disc
by gringer, published
An 8-way connecting disc. Prints fast.
My great uncle brought a multicoloured set of about 100 of these back with him from Taiwan about 20 years ago. I can now finally make some to replace the ones that we've lost over the years. I was reminded of these when I saw the lockable poker chips. These are essentially the same thing, but a bit smaller.
Print out many copies of the STL file, and make a huge bundle of different constructions.
Multi-piece models are also provided, which double as bed-level calibration devices. The shapes should be 25mm diameter, 2mm thickness.
Two alternate models are provided, one with an extruder overprint expectation of 0.25mm (works well for PLA), and one with an overprint expectation of 0.15mm (works well for nylon). For further experimentation, see the OpenSCAD file.
