Review on 🖨️ Efficient Screw Thread Diameter Printer by ReliaBot: Enhancing Precision and Performance by Nick Kirschenmann

Decent quality pair, not too much play in the lead screw nut but the springs are very weak when used under preload to reduce play. I guess they're all weak no matter who you buy them from. You'll need to replace the 10.15mm ID x 55mmL and 16mmL @ full compression stainless steel nibs with something stronger as I can see these nibs don't work too well on a decent sized print without ghosting, especially when printing with many vector changes .
