Lens Cap & DIY Filter Cap for GoPro HERO 3 Waterproof Case

thingiverse

Initially, I discovered a leftover polarizing foil at home and decided to utilize it for my GoPro Hero 3 camera. To do this, I created a lens cap with a hole for the foil. With the resulting "DIY filter cap," you can use any transparent material as a filter by cutting it to size and attaching it to the waterproof case using the DIY filter cap. I designed two versions of the cap - one for thin films and another for thicker ones (approximately 0.5mm). Additionally, I made a version with the hole closed, which functions as an effective lens cap for the waterproof case. The design was created using SketchUp 8 and is optimized for a Replicator 2; however, it may need slight resizing to work well with other printers. It draws inspiration from bokehmans' "ultimate lens cap."
