This is a universal spool roller that will hold your filament while printing. There are a lot of spool roller designs out there, but this one is universal and never requires adjustment. Just grab your spool, drop it on the rollers, and you are ready to go!
The design works with any spool that is larger than 15cm (5.9in) in diameter and less than 10cm (3.9in) wide. This includes spools from MakerBot, Hatchbox, Inland, DFRobot, NinjaFlex, etc.
If you look at the pictures, you will notice one side of the roller has two black guides on it. These are meant to trap one end of the spool so that it can't slide down the length of the rollers. The top of these guides are slanted inwards to make placing the spool easier.
NOTE: I've received requests for a wider base to accommodate new 5Kg spools, which are too wide for the original design. I've added two new parts: Roller (Large) and Base (Large) which extend the design so it can now accommodate spools up to 4.5in (115mm) in width.

Tapping the holes first will make your life easier, but isn't necessary.
