I recently just bought a USB C to USB adapter since my Mac Book Air with the M4 chip does not provide many slots or any usb inserts, The brand I used is Anker a very well known and trusted brand. But there very little and can be lost easily. If you print this with any infill you would like even though I recommend %80 for more durability, you will have a very secure and protective case that will keep track of those adapters for when you need them most. Let me know what I can do or change to make this even better!

RECOMMEND USING ABS!!!!  %80 OR HIGHER INFILL

pla works fine also :)             lower infill level also works ;)
