Update 7/12/17: Added version 1.1 of the stl files, they have some issues corrected and should fit better.
Update 7/18/17 Added version 1.2 which incorporates screw holes for 2mm self tapping screws to afix the two pieces together rather than acetone welding.

I want these mods to be available to the community. They are all still in development, but I would like feedback from the community.

This is designed to mount a PicoPSU in a Dreamcast I designed it to acetone weld the two pieces together.

I had this made and Thank You!!!

Just a few thoughts:
1: The base is a bit too thin. it flexes easily.
2: The opening of the hole for the adapter is a bit thick? I am only able to turn the hex screw 1 full turn before it bottoms out. But it is secured.
3: On the smaller piece, where the Pico PSU mates with the atx connector, the opening is a bit tight.

Other than that, this thing is great!

Thanks for the kind remarks and the feedback.

I may add a bit more thickness to it so it doesn't bend so easy. I designed it with the same thickness as the original PCB.

The power jack at the back was designed to be that thick so that it is flush at the back I thought it looked better than the jack sticking out.

I made the atx mounting piece before I got an actual connector using their datasheet. I think the size issue is a combination of out of spec parts and shrinking material. I will probably go back and offset the hole by a small amount to make assembly more simple.

Thanks again for the thoughts. When I get some free time I'll make a few changes.
If you get some time I'd love to see your make you can post them here with the I made one button

I made a second print because I purchased another dreamcast. This time I went with a 75 micron print. The first was a 300 micron print. This second print at 75 micron came out really smooth and sturdy!! Although the long part is still flexible but it is definitely more rigid. Thanks for your contribution. I will post up some pictures.

Very awesome, what wattage PicoPSU are you using? Thanks!

Thank you, Its the 80w one from Amazon, official PicoPSU brand. I am using a 60w 12v brick which is more than sufficient for the draw of the Dreamcast
