Summary

These simple "Panel Clip" clips allow 1mm thick 15" x 11" kitchen chopping mats to be used as front and side (when trimmed down to 9" x 11") panels to keep draughts out of the printer.

The "Top Clip" parts allow a plastic storage box to be used as a top cover. This is meant more as inspiration rather than for direct use as you'll need to design one to match whatever box you have available.
