6mm Tube Makergear M2 Filament Guide Support Arm for 1.75mm filament
thingiverse
Two sizes are available, with 6mm working great in conjunction with 6mm OD teflon tubing that I highly recommend as it consistently provides the least restriction even when using 1.75 mm filament. If your filament happens to have any bends when coming off the spool that puts restriction on the extruder as its being pulled through a small tube, give the extruder an easier time by utilizing the 6mm OD tubing. Buy the tubing from McMaster Carr, this is known good quality tubing, unlike the unknown stuff you can get on Ebay. Only $2.75 a foot as of March 2017. The other legacy file is designed for the 3mm tubing that is stock on the Makergear M2. Also included is a simple adapter that allows the 6mm tubing to attach to this extruder: http://www.thingiverse.com/thing:344950 Youtube video covering my various Makergear M2 Mods: https://youtu.be/jD6ZTcCd0j8 By - http://www.easybotics.com/ And - http://hilo90mhz.com
