Ender 3 Filament Spool Extension

Wanted to make my own accessory to my Ender 3 Pro and ended up making a filament spool attachment for the stock spool for the Ender 3 series (I have no idea if the same cylinder/locking mold is used in the other Ender series).

Add-on acts as a stock Lock Ring for the stock spool holder, while having it's own spool holder for dual-action, or ease of swapping.

Notes:

Originally created April 6th, 2021

I kept in mind supports throughout the modeling process, so intended printing orientation is Lock Ring face down. That way the only support necessary will be for the two small peaks that lock the cylinders together, and can easily be removed with pliers/your finger nail. I didn't want the printer spending too much time printing supports over the entire thing, and additionally the hassle of removing them.

I used 100% infill, lower it to your discretion, the cross beam in the center of the beam should provide adequate support for the piece.

Can hold 2 filament rolls equaling to 2kg of weight

Due to a recent review the model files have been reassessed and revamped to properly fit the stock spool holder as intended. Thank you to Svenn Inge for leaving a review and making me aware of this dimensioning issue. The only file available to download now is the Updated one.
