Replacement Reset-Interrupt switch for a Mac Quadra 700, original part number original part number 815-6270. Possibly the IIvx, IIvi, and Powermac 7100 as well, but their part is slightly different and this one might not fit exactly right.
Measured and modeled by hand, it should be almost exactly like the original when assembled. Unlike the original part, I modeled the user-facing button ends as separate peices to make printing the overall assembly easier.
The little buttons have a little recess on the back that should fit onto the stalks on the main assembly, but will require an adheasive to secure permanantly. I printed mine out in PLA and used superglue, which isnt the best combo, but so far i've had no issues. ABS and superglue should be an ideal bond and probably the best way to go for this part. Note: The Interrupt button (with the circle on the front) should be be on the right side, and the Reset (triangle) on the left. It's a little hard to make out in the pictures, and it's not going to cause any issues if its off, but there it is just for the sake of accuracy.
I also printed mine on its side, so the layers are going with the spring action rather than against it, to prevent potential breakage.
