Simple Test Tube Rack

thingiverse

A Standard Tube Holder with Room for Five, 23mm Maximum Diameter. I built my one from Acrylonitrile Butadiene Styrene. In retrospect, since these machines can now rapidly print functional products (rapid prototyping is outdated), I would design the legs to be more robust. This is why I included the original model file for users who know their way around Blender. No raft was used during this particular project - please follow instructions! Print it without modifications; on my machine, a Rep2X, I typically require a support base but have since learned that making the initial layer thicker can prevent this necessity. To do so, decrease the entire model's position by approximately 0.07 millimeters. This allows for an optimal print foundation that prevents nozzles from becoming stuck or skipping on higher areas - tailor adjustments according to personal preferences! Upon completion, apply a single drop of acetone (cotton swab helpful in this situation) onto each leg where it resides in its corresponding socket. Care should be taken to maintain complete stability during the bonding process; acetone quickly dries and evaporates, causing parts that were just secured to become disassembled once movement occurs. That's all!
