BetaFPV naked case ND filter and accessories

cults3d

The BetaFPV case for naked gopros does not have a good ND solution. I've made this one to use both TBS and FPV Cycle filters. 36x33x2mm. They're slightly different so I have files for both. Also you will find a lens cap and a lens protector. Any part that goes onto the lens (Clips, guard, cap) should be PLA or PETG 0.2mm about 20% infill, can use supports for the lensguard. The "band" that secures the filter should be TPU. 0.2mm 20% infill is fine also. WILL Need supports. MAKE SURE to clean all supports thoroughly else the filter will not fit well! 1) push the Clip through the Band from the front of the Band (front is the side with the small lens protectors) 2) starting with a clean ND filter place it in the front and put your thumb in the middle - can use lens paper here if you want to or just clean it later 3) push with your thumb (do not touch from the backside) and use the raised edge lens protectors on the sides as leverage to get the edges around the ND filter. 4) When all 4 sides are over the ND, press the edges of the Band to make sure it's on tight 5) clean the front of ND filter with a lens wipe. I use alcohol lens wipes.
