This is the perfect tray to help with folding your shirts. Fold the sides in and then fold the bottom. Folds shirts faster and uniform. There are two sizes. If the first size does not fit add the extensions to make it bigger.
Printed Great using Bambu Labs PLA Basic with a PEI textured plate on a X1C. The missing extension pieces are in the download files as a seperate file. So you can add it manually to the Bambu File if you want.
