SummaryI liked troycavalieri's thingy. Just had to make it into a keychain :-)Print SettingsPrinter Brand: RepRapPrinter: Prusa i3Rafts: YesSupports: NoResolution: 0.2Infill: 100%Notes: Probably could get away without the raft, but as there is so little contact surface and my prints tend to curl up at sharp points, I decided to rather be safe. Infill of 100% was purely because of aesthetics as I printed it in clear PLA, 10-15% should be more than sufficient.How I Designed ThisJust a little rework on the original from troycavalieri done in 123D Design
