Casio SA-21 Battery Cover

thingiverse

This is a remix from Takuya's "Batery cover for Casio mini Keyboard". I modified the dimensions (It's almost the same) the hinge and the locking mechanism to make it work on a CASIO SA-21 that I have. It's far from perfection but it works for me, I printed it with PLA 0.2mm of layer height, fill 20% and supports. Depending on your printer you maybe need to activate "brim" option in Cura to sure the supports don't get loose, if your plate is clean and have good adhesion i'ts not necessary. The first time you use it maybe you hear "Clack", it's the hinge creaking, depending on the strengh of your PLA it will last more o less time. I use the typical Amazon's PLA and at the moment it's fine. Thanks takuya for the original model.
