I was researching replacements for LM8UU, one of the solutions use 3D printed from PLA. I try it before, but it was a challenge to make them perfectly feet on smooth rod. I found some trick end would like to try it in next build of MP3DP.
Just finished printing set of LM8UU from clear PLA. Picture attached, will let you know how it goes.
