Lulzbot Extruder Beefy Idler Block for Greg/Wade style extruders - Heatset Insert Edition

Here

This is based off the latest 0.4 Beefy lulzbot Idler variant (which compared to 1.4c is basically 2.0 anyways), licensing is Creative Commons Open Source Attribution as usual. Please feel free to use this part in any manner you see fit. If I can save one person from the agony of a stripped idler arm nut socket, then it will all be worth it. If you are retrofiting an existing extruder, you will want the beefy style idler latch as well here: http://download.lulzbot.com/Mini/1.04/production\_parts/printed\_parts/beefy\_idler\_latch/

Instructions: insert one M3 heat set insert (http://www.mcmaster.com/#94180a331/=13ettuz) into the hole in the side of the idler. Then install it using the stock mounting hardware and bearing insert thingy in the stock locations.

This will fit any of the Lulzbot extruders, for all the AO-10x variants, the Taz variants 1-6, and the Lulzbot Mini. it should also fit most other Greg/Wade style extruders

Edit: If your existing idler bolt does NOT have threads all the way up, you may need to replace it with a new 25mm long M3 Cap head bolt. You can find them here: https://www.amazon.com/M3x25mm-Screw-Socket-Screws-100Pcs/dp/B0143GZQNW/ref=sr\_1\_1?s=industrial&ie=UTF8&qid=1469314964&sr=1-1&keywords=m3+bolt+25mm
