UPDATE: filamentGuideV2 file. ( see 2nd photo for updated part)
3 reasons: 1) I broke a few of the initial filament guides when moving printers around. 2) New width of the part makes for easy sizing of 1kg reel spacing (reel holders fit snug against the guide for perfect distance). 3) Install upside down so when you have prints that max out your Z height, the filament has room to move around without breaking. Enjoy!
If you have made this thing, PLEASE take pictures and post! Thanks.
As more projects pile up on our workbenches, it was time to get the reels mounted to our printers for extra space. Here is a reel holder that is solid enough to hold a fresh 5lb reel but adjustable to also accommodate 1kg reels. It is designed for "Mendel-style" 3D printers that have a 3030 aluminum extrusion on the cross bar. Having the bearings mounted independent of each other provides extremely smooth feeding action.

The shape will lock the reel holders in place on the extrusion and I added a little plastic washer that is built into the part. You can adjust the width to accommodate either 1kg or 5lb reels.
Filament cleaner mounts on the front. The filament cleaner is just a rag with a binder clip but works amazing!
