Universal fillament reel holder

thingiverse

Here is a filament reel designed to fit nearly all sizes of those troublesome inner diameter filament reels. The holder utilizes two skateboard bearings inserted into the bottom holder cone and then placed over the 7mm hub pin. For optimal tension between the two cones, it's recommended to use a hair band, elastic band, or something similar. The result is extremely functional and I've been using it successfully for over two months with outstanding results. There's significantly less strain on the extruder and it's a very attractive item to have near your printer. I highly recommend securing all the legs firmly into the boss using super glue, then gluing the circular plate to the bottom of each leg to prevent sagging of the holder. When loading a new reel, simply remove the top cone, pull the elastic band around the bottom cone, and then pull it through the reel to keep it in place while you attach the top cone and secure the elastic over that. And there you have it - your new smooth-running filament holder is ready for use. Message me for any additional information.
