Reinforced A8/AM8/Prusa i3 X-Axis Tensioner

prusaprinters

The original part was a bit difficult to get the nut in the trap due to the hole printing too small, and once I had it in the printer and tightened down, the pulley mount cracked. I've made it 1.5 mm larger at top, bottom, and left, the nut trap is enlarged 0.5 mm so that it's less likely you'll crack that end of the tensioner getting the nut in, and the hole for the tensioner bolt goes all the way through. Print Settings Printer: AM8 Rafts: No Supports: No Resolution: 0.2 mm Infill: 70% Filament: eSun PETG solid purple Notes: Use 3 perimeters and a higher temperature than you might normally use (try the higher end of the temperature range specified by your filament; for me, that was 250°). It might not be a bad idea to print two, so that you have a spare on hand if something happens to the first one you install. Category: 3D Printer Parts
