Nextruder Nozzle (x9) Case Holder for Enclosure

This is a remix of the Nextruder Nozzle Case Holder for Enclosure, redesigned to improve storage capacity, stability, and integration inside the Prusa enclosure.

With this version, you can store up to 9 Nextruder nozzles directly in their original boxes, keeping them protected, organized, and always within reach.

The holder mounts inside the Prusa enclosure and features a curved cutout under the base to allow cables to pass cleanly underneath.
Thanks to the wide footprint of the base, the support is extremely stable and requires only one mounting screw.

Mounting

Fixation using 1× M3 square nut and 1× M3x25 mm screw

The square nut is pushed into place using an Allen key or a screwdriver until it aligns with the hole
(anyone who has assembled a Prusa printer will feel right at home 😉)

Bonus

I also provide the PrusaSlicer project file, which includes negative volumes allowing you to store the following tools directly in the enclosure:

Printing details

Printed in Prusament PETG

0.4 mm nozzle

0.2 mm layer height

When printing the version with negative volumes for tools, pay attention to the longest bridge, especially above the scraper slot.
On my Prusa MK4S, the part printed successfully without supports, but the bridging distance is relatively long.
Depending on your printer, material, and cooling, it may be preferable to add supports for this area to ensure a clean result.
