TR8 Lead Screw Block - IGUS

thingiverse

This leadscrew block serves a TR8 4 start 2mm pitch lead screw - the standard issue for many modern 3D printers. By design, this part eliminates backlash altogether. While created to pair perfectly with IGUS tribo-filament, it performs admirably in PLA as well. Given its tendency to wear out more rapidly, printing a few is recommended. Should you choose to incorporate it into your project, detailed dimensional drawings and STEP files are included. However, do keep 3D printing tolerances in mind; avoid tightening the part too snugly on the lead screw to prevent strain. If in doubt, prioritize a looser fit around the block's sides, with tighter fit ensured through the two aligned protrusions. Ultimately, it's pressed firmly into place within a retainer, offering both mounting options and increased rigidity.
