Pipe-Based Dice Tower

This is a modular stackable dice tower based around 3" ABS sewer pipe, or any tubing with similar enough dimensions (3" inner diameter, 0.25" wall thickness); additionally, you will need a 1/4-20 hex bolt or threaded rod and appropriate matching hex nuts. The tower's height can be whatever you want it to be; the central pieces are 0.75" tall and identical, so you can just print more or less to fit any pipe length that is a multiple of 3/4".

For my test build, I used a 6" pipe segment and 8 ramp pieces to create a roughly 8" tower. For the center bolt, I cut an 8" piece of threaded rod and used rocksett to semi-permanently attach a nylon stop nut on the bottom end of it, then used another stop nut (in the "king nut" piece) to secure the whole stack together from the top. (1/4" hex bolts over 6" were not readily available locally)

I printed all pieces at 0.28mm layer height for strength and to print faster. The base, roof, and ramps were printed at 25% infill, and the king nut was
