DNA Test Tube Holder
thingiverse
A microcentrifuge test tube holder in the shape of a DNA molecule. The holder holds 10 tubes. The base is 4 inches in diameter and the holder is 6 inches tall. Instructions The base pair rungs are printed separately and then inserted into slots in the strands. I eventually super-glued the rungs into the ladder to stabilize the holder. Each rung took about 15 minutes to print and the strand took about 10 hours.
