Blitzwolf BW-SHP6 flash adapter with two switches

thingiverse

Earlier this year I printed RobinSt's great design, but I encountered two problems with it: a superfluous space for a DC-DC converter that I didn't need and no room for a second switch to disconnect GND and GPIO0. I wanted to ask Robin for the Fusion360 files, but then I saw that he had posted the Fusion files back in September - thanks so much for sharing! I managed to fix the issues by removing the extra space for the DC-DC converter and adding another switch. It's not the most visually appealing design or print job, but it works perfectly. To limit current, I soldered a resistor (470 ohm) between the GND and GPIO0 - that was a helpful tip from an expert friend, even if I don't fully understand the reasoning myself!
