This is really cool! I like the attention to detail on the front panel, it's something I'd be proud of showing on a carefully built retro PC. I could see using this over CF to IDE adapters which work well but this is a cleaner solution.
Good luck with your launch, I'll be happy to order one!
Personally I think the half-melted (literally) rough 3D-printed look is rather ugly, and would prefer a stamped steel plate --- like this (floppy emulator): https://lotharek.pl/productdetail.php?id=28
On the contrary, I think you’ve done a fantastic job with the enclosure. Far from looking “half melted”, you’ve made good use of the bed texture, and the design is top notch.
as an aside to anyone else reading this, laser cut and bent sheet metal has gotten pretty cheap and easy, I think you could have an okay (unpainted) tray/case like this made for maybe $5 to $10 at 100 units
BTW I'm pretty well versed in getting laser cut and bent sheet metal made, both in China and via US-based providers like SendCutSend - my PicoIDE project uses a metal bracket. In fact when so many other projects were using 3D printed brackets, I decided that was not good enough and dove in and did the work to get nice brackets made affordably. It really elevates the project to a higher level of professionalism.
That being said, $5-$10 sounds about right (if maybe a little on the high side) for something the size of PicoIDE, but unfortunately that is too much for the price point I want to hit. Affordability is a major target for PicoIDE. And also, WiFi is a feature of the front panel and for that reason, metal is a no-go. The WiFi antenna is at the front of the device to give it the best chance of decent reception, so it needs to be plastic.
Good luck with your launch, I'll be happy to order one!
