I made a side table for my son's Weber BBQ using leftover 2x2 deck railing balusters/spindles from another project. Might have rounded the legs if I knew ahead of time how hard it would be to find square feet for the leg bottoms.
Sain Smart TPU
Speed 1800 mm/mn (30 mm/s)
Hotend @ 225 Bed @ 80 Part cooling fan 60%
I designed this in Fusion 360 and the f3d file is included. I'm quite pleased with the results in TPU, although good results with TPU from my Ender 3 requires ridiculously slow print speed
The ID is 33mm which works well with 1-1/2" balusters after they were sanded and finished. There is a drain hole in the bottom but I attached them with RTV sealant.
