LM2596 Buck Converter Case-mounts on rail.

thingiverse

No screws needed! UPDATE! If you downloaded it when I first uploaded it I accidentally uploaded the base for one of my other first attempts of this design. I have corrected and replaced the file. IF you have a base with two tabs sticking up by the hole, please delete it and download the buck and switch base file. I created a buck converter case with or without a area for a switch. It mounts in the rails very tightly(sorry) and fits the buck converter linked below almost perfectly. The access holes are almost perfect. Its designed with no screws needed. There are pegs that go through the board and into the lid. I designed these to be superglued into the lid. If you need to get back into the case after glued the pins will break. I just couldn't come up with a better way to nest the two pieces together. You will see in the pics, i had a pin for the mode button that didnt line up or fit quite right, and caused more frustration than it was worth. It could easily be designed to be better but I already glued mine together. The hole is 4.5mmx4.5mm if you want to make a peg to go into it.
