I needed a place to store all my MUTANT enabled hot ends, now that they were so easy to swap out. So I took the Fixed Plate Dummy model from the Wham Bam Systems support page (https://www.thingiverse.com/thing:4904718) and trimmed away all the bits I did not need.
Easily mounted on the wall or a french cleat mount to keep them at hand without cluttering up the workspace.
Printed in PLA with 3 perimeters.
