12mm test tube base

SummaryThis design is a series of 12mm test tube holders. It is designed to be a snug fit to hold the tube even if it falls down (nevertheless its 4 side legs gives it a very good stability). If you prefer the fit to be looser or if your printer has large tolerances (more than 0.3mm) you should scale the part to 102-104%.It can be printed without supports.
