Simplest cheapest enclosure for 3D printer

Made it so its simplest. You just need five 50x50cm panels 3mm thick from whatever.

I used 1 from acrylic and 4 from plywood. No tools needed for assembly. You will need to print at least 8 corner parts and at least 4 pairs of edge parts (these interlock together to hold shit straight). It has clearence along edges by design, so the whole thing does not overheat.

Printed fine in PETG with 0,8 nozzle. Tested clearence with my Anycubic i3 mega, spool outside.
