External light for diving photography (first prototype)
prusaprinters
The model is unfinished - I designed a prototype of magnetic switch that gets jammed often. This needs to be redesigned.The main part fits 1x 18650 battery, front part needs MK3S heatsink for completation (use an old, damaged extruder parts). The heatsing works great for powerful LED to cool, especially in the water.Sealing requires some postprocessing - you can use superglue, SLA resin, Silicone caulk etc. to seal all the holes and contact parts. The lid with thread is designed for 2 O-rings. Don't forget to use a silicone grease on them before every use.Don't forget to read my article about waterproofness to find out more: https://blog.prusaprinters.org/watertight-3d-pr…ing-part-2_53638/
