Five test tube holder (modular)
myminifactory
A five test tube holder for the 16x150mm test tubes or equivalent. The design allows for the top and bottom parts to be printed separately and then joined to together with a 'key' piece that is also printed. This modularization also allows for safer packing and moving of the holder(s) since the vulnerable narrow center could be broken if it was a solid piece. There is a decent amount of space between each tube allowing for ease of handling. The divets at the base of each tube hold the tubes in place quite well.
