Prusa Core One bottom print sheets storage

Introductions

I couldn't let the prime estate under the printer go to waste, so here is a print sheet holder that mounts at the bottom and holds four print sheets.

The model utilizes M3 holes in the bottom plate and uses four screws for mounting.

Slots are angled upwards a bit, so the sheets won't fall when shaking during printing.

Required prior modification

This model requires feet to be added to the printer. Compatible models include, but are not limited to:

• Prusa Core One Squash Ball Feet by @dancan13f;

• Prusa core One feet v2 (apart from “angled” versions) by @Prusaguy;

• Prusa core One feet v2 - Squashball Version - Anti Vibration by @TPdesign;

• Prusa Core One Feet 30 mm high by @ChristianEM;

• Models that:

• leave at least 30mm gap at the bottom;

• have xy dimensions similar to this model (it has less than 1cm horizontal gap to the holder).

Required hardware

• 4 M3x4 or longer screws

• rT screws (e.g., M3x4rT) work as well;

• print the spacer model if using longer screws, so they don't stick out into the enclosure.

Print instructions

Models are pre-oriented, so that they can be printed without any supports:
