This is a snap fit case for a cheap DIY tube amplifier soldering kit that comes as a bare PCB.
I got the amp to go between a Bose 2.1 speaker and even older record player. The amp is fun to look at and the sound is ... ok. It also needs a ground loop isolator. For the price it's not going to please any audiophiles.
I printed the case in "clear" PETG and after lots of attempts I can get it sort of translucent. The goal was to see the components inside but for the most part you can only see the LEDs. From Slic3r PE I changed the angle of the infill to be in the same direction as the edges (the default is tilted 45 degrees) this helps it be as translucent as possible.
I uploaded the fusion 360 file so go nuts and remix it if you can do better.
Front, back, and top are pretty straight forward.
The bottom plate needs to be printed on its side, tall and skinny, with a brim. Fan on high since it has some slight over hangs.
The text on the front and back plates will come out better if you use a .25mm nozzle instead of a .4mm. I did that for one iteration and it looked better but I forgot to change back to .25 for the last iteration. Contact me if you want a plate without any text.
