Description

Wanted to create an easy to print and assemble spool holder for 3kg filament rolls.
Uses 4 pcs 608ZZ bearings which are very cheap to buy.
Make sure to print this item in basic PLA and not the weaker matte/silk filaments.

Supports filament rolls with a diameter larger or equal to 250 mm.
Supports filament rolls with a width of smaller or equal to 125 mm.

Assembly instructions:

Press the 608 bearings into each end of the roller pieces.
Screw the rollers together,
Place one Side piece with the bearing pins facing upwards on a table.
Place the rollers onto one side piece, then put on the other side piece, and then attach the two connectors that lock everything together.

Here is a little animation of assembly:

Has the following features that I tried to improve over existing solutions

Rollers print in half, easy to print on bed-slingers like A1.
Low profile, with 250 mm rolls, clearance from ground is 5 mm.
Bearings not exposed, avoiding risk getting bearing oil on your hands when it is assembled.
Easy to disassemble when not in use, saving space.

Thank you!!! Great model. Printed fine from the 1st attempt. All tolerances are great, it assembles easily. The low profile is a valuable advantage. It is strong enough for the 3 kg spool and is easily rotated to print without any issues (Bambu P1S and A1Mini have been tested).

Printed perfectly! My filament ran out though so I suspect the male rollers was not fully printed but it did not seem to matter. Thank you for your design!

Question: can the horizontal rollers be lengthened to slightly more than 150 mm? The 3 kg roll I bought is 150. I tried to scale the z-axis on each half of the rollers in Bambu Studio but I think that will mess up the threads.

The designer has replied

@Paw85

I dont think that will cause any issue unless you elongate it a lot. up to 5% I dont think will be any trouble? Maybe start with one roller to test? Edit: Also make sure you enlarge the length of the beams connecting each sides as well, the equal percentage, as well as the thickness of the sides (basically enlarge every detail the same percent in the same direction), then it should fit :)

This has solved many issues for me using the external spool. Absolutely flawless print and easily put together

@drageset

Hi. Just curious, the 3kg eSun PLA+ filament roll is 270mm in diameter. You did not have any issues using it with this model?

Came out nice and clean. The only thing to consider is, it's pretty hard to press the ball bearings in. But when those are pressed into their places, it rolls like a charm.

Thank you for taking the time to leave a comment. The interference fit has three ribs with a minimal amount of interference to the ball bearing. On most of my prints, I can easily press the bearing in with my thumbs, but once in a while it has happened that it has been a bit harder. I then put the bearing on the floor, and pressed the printed part down on it instead. The fit requires that the filament is calibrated well to get it to work well, easier on the A1 as it auto calibrates, but sometimes the filament diameter varies enough to cause these issues as well. I am glad that you got it in there thought and Ill see if there's a better way in the future to make these things easier to assemble!

Thank you. It printed beautifully and it was exactly what I needed for these 3kg spools that I just now started buying. I appreciate you.
