MP Mini Select Perpendicular Spool Holder

thingiverse

The stock reel holder for the MPSM requires the filament to make a hard turn at the top of the printer to go into the extruder. It's also square. This causes all kinds of extra drag which nobody needs. This is a reel adapter that attaches to the side of the MonoPrice Mini Select 3D printer where the stock reel holder goes. It holds the spool so that the filament comes over the top and straight into the extruder. It also features a ball-bearing mounted reel that can be sized to the core of the spool(s) you use, meaning that it doesn't hop and drag on the reel. I've also included a spool that you can attach sides of whatever size you need, and use a 1" reel through its core. I use this for the $5 Filament mini-coils. Just slide them on and go.
