I got tired of the pattern strips sliding around so designed a tray to hold them. The OpenSCAD code used to create them is also included. If you want to make the holes in the tray smaller, adjust `cavity_padding` in the code and regenerate. Also consider making `tray_bot_h` larger if you want the base of the tray to be thicker. As included here, I found the resulting print a touch flimsy but they have worked well!

At 245 mm x 239 mm, this is a large print. On my BambuLab X1C, I had to follow the below instructions to utilize the full print bed.
