HyperCube Volt Meter Mount
thingiverse
Got worried that the E3D cooling fan would stop suddenly and damage the printer. Bought a couple of cheap volt meters to keep track of everything and needed a mount. The plan is to have the three volt meters checking the E3D fan (12V aux pins on the RAMPS board), heated bed (since I'm using a relay) and the E3D hotend. You may of course use them for whatever. The mount is assembled using 2x M3 nuts and bolts (13mm+ length) and mounted on the standard 2020 aluminium extrusions using 2x 10mm M5 bolts and T-slot nuts. I recommend using a ball-tip allen wrench for the top M5 bolts since the angle of the mount blocks straight vertical tools. The mount should fit most small digital volt meters which has a display size of 23mm x 15mm.
