Description
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)
