ClipSpool - Bambu Lab Logo

After recently switching to only buying filament refills from BL where possible, I decided to design a spool to meet my needs, and get rid of my box of filament clips.

This is designed to be compatible with the Bambu Lab's filament refills, including the little nub for preventing the cardboard inner from rotating freely, with a 55mm inner diameter, and 200mm outer diameter. The filament labels pop in and out, but still hold securely.

The two halves of the spool thread together and friction keeps them locked in place. I have printed more than 4kg of filament using the different versions of the ClipSpool, and had no issues whatsoever.

Filament Clip

The filament clip channel run 360 degrees around both halves of the spool. The channel is slightly wider that the filament, but the shape of the channel keeps everything securely in place. No more cutting off the deformed end of the filament, and it pops in or out with very little effort.

The filament clip channel is identical on all versions of the ClipSpool. Video below shows how easy it is to lock the filament with one hand (video shows the Hex version - didn't make sense to make a new video for each version).

Filament Label

I've found that I wanted to be able to quickly pick out some filament without wondering if it's Basic or Matte… or even PETG.

You can of course put your name on the filament label instead, especially if you have a shared printer. I've included a blank label so that you can pop in to Bambu Studio and add your own text. I've also included a little label holder, so you have somewhere to store them. I print labels in bulk to avoid wasting too much filament with colour changes.

The labels also pop in and out with a satisfying click… and the labels fit all versions of the ClipSpool.

This project took a long time, and many many test prints using several kilos of filament trying to get everything right. If you like the model and want to support this and future designs, you could buy us a coffee, which would be greatly appreciated. https://ko-fi.com/kobariley
