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.
Here is a list of the parts you will need, including ordering links and cost:
Tapping the holes first will make your life easier, but isn't necessary.
See post printing for assembly instructions!
0.1mm or 0.2mm
Step 1: Insert bearings into rollers.
The roller cylinders are designed so that the 608ZZ bearings can be press-fit into each end. It will be a little tight (by design), so just put your weight onto it or use a hammer lightly to press the bearings into place. They should be flush with the outer edge of the roller cylinder.
Step 2: Tap holes (if you want).
If you have an M2.5 tap, you need to tap all of the holes on "Brace A" and "Brace C". These are the two outermost guides.
Step 3: Assemble rollers and guides.
The two outermost guides, Braces A and C, have axles that are also supposed to be press fit into the bearing. These should be a little looser than the roller cylinders, so don't worry. Press the roller bearings onto Brace A. Then slide Brace B over the two rollers, and use the M2.5 screws to attach Brace B to Brace A. There should be 6 screws to attach them together. Finally, press Brace C onto the other end of the roller bearings.
Step 4: Attach the base plate.
Finally, use the M2.5 screws to attach the base plate to the guides. There should be 12 screws use to attach the base plate. If you have the rubber feet, now is a good time to attach them to the bottom of the base plate.
If you have any questions, please comment or message me. Enjoy!
