I recently installed a more powerful blower fan on my delta (for the electronics case) but damn if it doesn't sound like it will take off. To tame the fan a bit I needed a PWM controller (for a 3 wire fan). I ordered one like this, and made a case for it which will also have space for three illuminated switches. I'm still waiting on parts so am not 100% everything will fit, but I printed it anyway. If it works out when I get the rest of the parts, it will get posted up to Thingiverse.

The final version of this is now posted on Thingiverse here. I say final, but it is still a "work in progress", still I think it will be the last revision of this model since everything seems to fit so far (still waiting on switches). There is also a face plate which is purely cosmetic that is being printed right now (so no pics of that yet).
Below are some new pics, I have it mounted on the delta and the PWM fan controller is doing a good job of keeping the blower under control.
