This is a case for the Logitech MX Master 3 mouse for transportation and storage. If I'm correct, the MX Master 1 and 2 have the same dimensions and fits as well, but I can't confirm this.

It is designed to print without support and with 0.4 mm nozzles as well as 0.6 mm nozzles. The lid attaches with eight small magnets that are glued in place.

It also contains a slot for the USB receiver. However, If you don't get a good fit with in your print, there is the USB-Holder Backup file added which you can tweak for a perfect fit. It prints fast and can be glued over the original slot.

Additional Material required:

• 2x2mm round neodym magnets - 8 pcs
• 20mm round felt pads - 2 pcs
