This is a case for the Flipsky Dual FSESC6.6 Plus. It is designed to mount to two of the mounting bolts for a skateboard truck, (mountainboard or standard).
This Thing is still a work-in-progress, and should be considered "beta" until I finish designing the closure mechanism. Suggestions are welcome; I love feedback and I'm still learning OpenSCAD. This is also highly un-optimized; I'm sure there are better ways of building the design such that the render happens much faster, but I have no idea how at the moment. If any OpenSCAD guru's can comment, I'd appreciate it.
UPDATE: 2019/09/19 - Removed screw holes as they were a bad idea, (My printer's tolerances are not tight enough and the holes mostly filled in), I'm now trying ball-shaped indents/protrusions as a way of snap-together closure. Will likely revise this once again after testing this weekend with printed parts.
This isn't so much a remix as a ground-up redesign of thing:3695975 in OpenSCAD. My power switch was larger than the hole provided and I wanted to make the entire enclosure taller as well as add cutouts for the hall sensor wires, specifically so they wouldn't run parallel to the phase wires out the back of the enclosure. In addition, I wanted a cutout for my Heltec-based Firefly Nano Remote receiver.
This case is very much far from waterproof, or even water-resistant, so you'll want to start by adding a conformal coating to the FSESC board to protect from shorts. I have a few ideas for how to properly seal the case, however for now I won't say how until I've had a chance to test a couple options.
