This Core One/+ mod enables the placement of a PolyMaker PolyDryer box in the side pocket without removing the new Core One + spool holder attachment.

The shelf parts are designed to hold a lot of weight, with reinforcement of the extended part that enables the box to sit securely in the side pocket.

The shelf attaches with magnets and is therefore not compatible with the Core One L

This model pairs well with the spool holder mount I've design:

Materials & Print Settings

You'll need 6x Ø10mm x 3mm magnets. You should use strong magnets as they are carrying quite some weight.

The magnets should fit without the need for glue, but a bit might be needed.

Print Settings

I've printed mine shelf in PETG to allow for a bit of flex if needed. With that said, it should be fine if printed in PLA as well.

The part should be printed on its side and you'll need support for the upper rear wing. No support is needed for the magnet pockets. I also used a brim to ensure minimal warping, but that might not be needed.

In order to ensure a strong part I used 4 outer perimeters.

• Filament: PETG

• 4 perimeters

• 15% infill

• 0.2mm layer height

• 0.4mm HF brass nozzle
