Clam shell protective case for Logitech MX Master 3 & 3S.

Magents

• Fits together with either four 4x4mm or 6x3mm magnets. Choose the right files below.

Location Pegs

• Cut 2x 8mm lengths of 1.75mm filament. Press fit or glue into the small holes on the Back Case

Protective Liner (Optional)

I was worried the 3D print would rub on the paint and rubber of the mouse over time, so lined the inside with some 0.5mm adhesive back silicone I had, slightly thicker/thinner would also work. I have added a .pdf of the unwrapped template to cut out and assemble yourself.

Model Update (V2)

• Holes made larger for 6x3mm magnets to fit without heat pressing
• Thickened walls around the magnets
• Added location pegs to align the 2 halves together, this means case can still be printed flat without support, see above for assembly instructions
• Thanks for the feedback on improvements to make

Print Settings:

• Printed 0.2mm layer height
• 0.4mm nozzle diameter
• Can print without support (depending on slicer and print tuning, I used near default settings on SuperSlicer and Bambu Studio)
