Repaired my L printer with TR10x2 Z leveling threaded rods.

Repairs to my L printer now boast a sleek upgrade in Z leveling thanks to threaded rods with Tr10x2 precision threading. Initially equipped with the lower-grade M8 rods that generated massive run-out errors on every single print. However, an easy decision was made to swap them out for a guiding system incorporating trapezoidal thread technology - and let me tell you, the improvement was almost instant. While those earlier rods were plagued by severe round-out issues at nearly every turn, their new Tr10x2 replacements boasted remarkably minimal errors that are nothing short of remarkable. However, one small challenge emerged in this ingenious design - getting the round nut from slipping its spot while threaded onto those sleek TR10x2 rods. You'll notice that there's no need for blocking pins or bolts to secure it firmly into place - just a simple matter of generating adequate friction between the printed guide body and the nut itself. Achieving the perfect balance is quite crucial, really. Use fine-grit sandpaper on your printer's internal cylinder guides before trying out this new upgrade. That delicate touch will ensure that when it does slide smoothly back-and-forth under spring tension (up & down movement should always feel effortless!), your threaded rod and nut aren't damaged by unnecessary friction pressure at any given time during operation. Despite sounding troublesome upon first inspection, I assure you this design performs marvelously every single day - a testament to human ingenuity in overcoming initial design hiccups with ingenious workarounds that actually end up working much better than the original plans might've ever hoped!
