The Shield Ecosystem
The housing kit is the foundation. Planks are swappable — pop them out and drop in a new set anytime. We're building a library of free, open-source emblem and plank designs that the community can download, remix, and share. Design your own crew emblem, family crest, or team logo and it slots right in.
STEP source files for the planks are included. When adding emblems or engravings to the plank face, apply a -0.2mm horizontal offset and -0.4mm clearance offset for a clean fit. Note: the handle is on the right side by default - orientate your emblem accordingly so it's the right way up when held.
Tips
PETG will permanently bond to smooth PEI - use textured PEI or glue stick
Test brass insert holes with a small test block before the full print
