Universal Adjustable Riser V1 and V2

This riser can achieve fixed step heights of about 10, 14, 18, and 22 mm by adding the layers one at a time. By combining and rotating the threaded layers, variable heights between 14 - 48 mm can be set. Originally, I designed the first one to be an espresso cup riser to prevent coffee streams from shooting out of the bottomless portafilter when channeling problem happens. Then I realized the riser is so strong that it can work as an Universal Adjustable Riser for many other purposes. I've tested it with a 52.5 lbs dumbbell plus heavy books and other heavy objects with no sign of damage (it was printed with 0.4 mm nozzle, 0.2 mm layer height, 10% infill, and 2 wall loops). You can beef it up by adding wall loops and infill percentage if you'll use it for heavier duty conditions. The 3mf file includes both version 1 and 2 on two different print beds:V1: Original design. Very smooth threading with polygon outer edges. Offering a simple look. Layers spin in and out smoothly.V2: Ti
