GoPro Session 4 Lens Cover

This is a lens cover for a GoPro Hero Session 4, designed in OnShape online.
I needed a cover that allowed enough space for the stick on lens protector I have.
If your printer is calibrated well, this should be a push fit to the front of your GoPro - I printed it using a Geeetech Prusa i3, and it fitted fine first time, with standard build board supports in Cura.
Any issues with fitment, you should be able to resolve with scaling.
