The file '16×160 Mm Test Tube Holder With 1,5% Incline 3D Printer Model' is (stl) file type, size is 16.2KB.
I couldn't find a stackable holder that fits my needs so I made this one. It's for 16mm x 160mm test tubes and has a 1.5% incline to prevent flooding, not sure if it's necessary but it can't hurt I guess.
