This is an upgraded version of the SKEWBITS board. The thicker board snaps onto the various cases which can be used to store SKEWBITS problems. There is also a cover that snaps over the top of the board, so you can store all the bits in one nice package.
The cover can be printed blank, or use multipass printing to include the logo on the lid using the LogoA.stl and LogoB.stl versions of the cover. The 'thin' cover can be used to close the problem containers instead of the Premium board. This is useful if you have a lot of skewbits problems, so they can be stored in multiple containers.
Containers comfortably fit 10,15,20 and 25 pieces. For more than than I would suggest using multiple containers. For best results, store problems flat one by one. PLA parts smushed together may deform over time!
