This camera cover prints in three parts, the window is 50mmx1,7mm plexi/acrylic and the screws are 6 M3 screws that are 7-10mm long. Use small amount of CA glue/super glue to mount the upper and lower part.

Remember to use UV stable material if you have it outside(PETG/ASA). This enclosure will obscure the edges of the image some what. 

Prints nicely with organic supports on the upper part.
