Multiple options here - joiner strip mount, wall mount, and window ledge mount.
CubeChallengeCoinMount - To be used with the CoinRingHalf of any thickness or diameter. Print two, with one reflected on the blue (z) axis. Fill percentage and layer height are flexible. Use a material that glues easily with solvent (ABS, ASA). Brim is not required, but support is recommnended. Remove the support, insert the nut and glue the two halves together. Attach a ring with a coin in it with an M3X10-mm flat head screw.
CubeChallengeCoinMountSinglePieceHeatSetNut - To be used with the CoinRingHalf of any thickness or diameter Print with support and brim. Fill percentage, material, and layer height are flexible. Designed to use M3 3-mm X 5-mm heat-set nut. Attach a ring with a coin in it with an M3X10-mm flat head screw.
ChallengeCoinCubeWallLipMount - Intended for use on the upper edge of the joiner between the upper and lower wall pieces on Haworth cubicles.
ChallengeCoinCubeWindowMount - Intended for use on the window ledge of the upper portion of Haworth cubicles. Also works for table top use!
All the holders and rings have their dimensions in the name. For the rings, use a material that is easy to glue with solvent. CA glue will work, but it will be hard to keep the CA off of the coin. Fill percentage and layer height are flexible. Print out two and glue together.
For the holders and mounts you can use your favorite materials. Fill and layer height are flexible. I have had good luck with printing the ChallengeCoinCubeWallLipMount and ChallengeCoinCubeWindowMount without support.
