These print flat on the print bed and fold together (using either a PLA fold or a print-in-place hinge) and flatpack, making them easy to print, store and transport!
Enabling ironing makes the top surface nice and smooth so the layer lines aren't a problem, they use very little material and print fast. The set (along with 2 others in different designs) is available for sale on my website here: https://warscape3d.com
