Filament clip for 1.75mm filament for plastic spools.
(EDIT : Added 3mm filament version, with 3.3mm hole. The 1.75mm version has a 2mm hole.)

Just bought a whole batch of different coloured ABS and wanted to try out the various colours without using a full spool. Just anticipated that unraveling spools will be a nightmare so came up with this super simple clip to hold onto the filament.

Didn't like the idea of tape or 'sliding it under'.

The flat side is deliberately on the inside as I've found the spools I have have the inside smooth (makes sense) and the outside rim is thicker than the inside.



2)Insert loose filament end into the hole
3)Clip onto the plastic spool
4)Profit from not having to deal with unraveling spools

Thanks a lot! Work perfectly

Thank you for this design! I tried a couple other similar clips, but they were designed for specific spools. This is much more convenient. I printed off half a dozen to keep in the supply box.

Elegant in it's simplicity. Thanks.

Simple and works great! Thanks!

I printed mine in PLA for 1.75mm filament, so I scaled it up to 125% and it fit both the filament and the spool perfectly. Thank you for this!

OMG people just take a damn 2mm drill bit and drill out the hole if it doesn't fit! Thank you for making this! It solves a problem I had :D

I love these things. I use a #50 or a #49 drill to smooth out the hole to fit my filaments as needed for a snug fit. Many thanks!!!!!!!

Great, thank you!!!

The 1.75mm version needs scaling. :(

As others have said, hole for 1.75mm was way too small. Most likely due to shrinkage of PLA.

Scaled the print to 120% and it just fits.

These are great, I tried multiple clips but this is imo the best design and holds really well.

Good item but the hole of the FilamentClipC_175.stl hasn't 2mm hole. Fix it please.

Made one, hole to small, put a 2mm drill trough it, perfect. Simples.

Really useful - thanks!

Had a lot of problems getting the 1.75mm to fit on..

Excellent! thank you

saw 999 collections. I just had to be #1000

Had a lot of problems getting the 1.75mm to fit on CraftBot, sliced with Craftware, fiddled with lots of settings, clip part is fine, just the hole is always too small. Finally went crazy and sized up to 125%, but then hole was too big. Gave up.

Printed a 3mm clip w/ PLA. The holes where just exactly right - but as my filament was molten at the front, it got a bit thicker and didn't fit in the hole again.
Also printed the next one 110% scaled up, which worked very well.

My frist two prints had holes that were too small, I gave them to girls in the office. They love their alligator tea bag clips! Haha, using it to hold the string on the tea bag.

1.75mm doesn't fit on MakerBot w/ PLA.

everytime this is the last print before swapping spools, so the spool will always have its own printed clip ;)
i love them

Scale Model to X=23.52mm, Y=16.41mm, Z=10.94mm then print. Clip fits beautiful and filament slips right in.

I printed the 1.75 version. The hole was just a smidgen snug, so I clean it up a tad with a 5/64 drill bit. Tested on three different types of spools and it works great now! Thanks Madox! :)

Printed the 1.75mm Clip on a Replicator 2 - Too Small! Filament didnt feed through the hole, had to resize the object a bit bigger!

Filament hole too small for 1.75mm filament? I just printed and it does not fit. How much clearance did you leave in your design?

Great clip. Can you post a STEP file? I would like to modify the clip a little to work with a filament spool I put together. I will make sure you get credit. Thanks!

I think my slicer settings may have been off because I ended up having to drill out the hole a bit so the 1.75 filament would fit, but worked great after that.  Thanks!

I had the same problem, could be cause by a close build plate but I found they worked fine when I just stuck the filament inside the clip.

Thank you for this design!

In addition to clipping filament ends to spools I've discovered other uses.

It's my favorite thing to test print new filament with (and nets a handy clip printed in that plastic to put it back on the shelf with).

It makes a great Y end stop adjuster for a PrintrBot! You clip it on to the Y rod and if you need more adjustment than that provides (I usually don't) you can put a 3mm screw through the filament hole! :-)

Thank you for this design. :-D

I printed out a bunch and they are working well. Thanks! Stacking is a little difficult, but that's a challenge for another day.

If you were to print 3-4 per spool, you might be able to distribute them and stack more easily.

Wow! What board surface is that? Prints OK without raft?

Perfect. If I hadn't found this I would have had to design one myself.

Simple but handy. 8-)
