85C1-A Ammeter Case -- for K40 laser or other applications

thingiverse

I decided to mount the K40 with the 85C1-A analogue ammeter externally and needed a case for it. My goal was specifically for the laser, but this setup will work just as well if you need an ammeter case for any other project. This case comes in two parts: a base that mounts to the laser, which has four bolt holes for secure attachment, and a top that holds the ammeter securely in place. The ammeter bolts into the top, requiring some care due to clearance issues, but needle-nose pliers make it easier. Then, the top is bolted onto the base using m3 bolts. All bolt holes are designed for m3 bolts, ensuring a secure connection every time. There's a hole in the base that allows you to run wires through, or you can choose to drill an extra hole in your project and use one of the two side holes at the base as an alternative.
