Take your happy little dumpster on the road with you! My recent coaster now comes in keychain form. The colours run through the entire thickness of the keychain so the image is double sided and it fits a standard keychain loop easily.
It was sketched/designed at a much larger size so the current scale is 20% XY to make it about 40mm. Feel free to go larger but check if the lines are all in tact after slicing before printing it any smaller. *The Z thickness is 2 mm and should not be adjusted*
