This model is compatible with the Sparkx I7 and the Creality Hi

My spool holder broke this year. I’d been relying entirely on the CFS, but then I fancied printing with some old, slightly brittle filament rather than throwing it away. The CFS doesn’t really like filaments that are a bit brittle, but no problem with direct drive.
So I modelled this new arm.

This model is stronger than the few existing models on Creality Cloud, but it is neither heavier nor takes longer to print (or very few). Adding a lattice structure not only makes the part lighter, but also, and more importantly, increases the number of walls, which is the most important factor for a part like this.

The original spool-holding shaft fits perfectly into it, and the whole thing assembles. If you need a new one, you can find compatible parts here :

It's ok (so far) with PLA, but you can off course use PETG if you need it to be more durable.

As this model is reversible, when used in conjunction with one of the guides linked above, it can make TPU printing easier on the Sparkx i7 too
