ND Filter GoPro Session Case (slide in): Jello Guard, Freewell

thingiverse

This is a custom GoPro Session case/sleeve designed specifically to hold an ND filter in place. The front of the case opens easily, allowing you to quickly remove the ND filter and select the correct strength with minimal fuss. The original design of this case was inspired by the TBS Jello Guard, but it has been adapted to work seamlessly with that product as well. A snug fit is achieved through a precise design, which provides excellent protection for your equipment. I have personally used Freewell Filters, which are high-quality products, but they can be quite fragile and prone to breaking. These filters measure approximately 33x36mm in size and come equipped with a quick-release mechanism that makes it easy to remove them from their case. Unfortunately, the glass components of these filters are relatively thin and may not withstand rough handling or accidental drops. To minimize this risk, I recommend obtaining replacement plans for your filters, just in case they do break. For weight measurement purposes, I use settings with 10-20% infill and one wall/side perimeter on each side, along with four to five top and bottom walls. This approach creates a spongy texture that offers better protection against damage than traditional solid walls.
