Custom Bench PSU Housing

thingiverse

A housing for a collection of electronic modules is required to create bench power supplies that take in AC power. This housing consists of: 1) DC2416 - an AC to DC converter 2) D3806 - a DC to DC converter 3) A Digital Volt/Amp Meter with Shunt 4) A Digital Thermometer / Another Volt/Amp meter? 5) A Double rocker switch Instructions: To assemble the housing, orientate the top piece either upside down or at 20 degrees to ensure it lies flat on its face with irregular shapes. Both orientations require minimal support. *Note 1: The holes are cut out with exact measurements. To compensate for the shrinkage of the material that will be printed, you'll need to scale it up to 102% - 103%. You'll need M3 screws to mount the two electronic modules and the shunt. The rest should snap fit into the holes. Stand-offs are not required. The DC2416 & shunt should be screwed onto the base. D3806 should be screwed to the top from the bottom of the module. The two halves should be able to snap fit together. *Note 2: Before you mount the D3806, you'll probably need to screw in the wire connections to the ACDC converter's output and output of D3806. *Note 3: Output holes for the D3806 are not in the design. You can install your own connectors. The PSU should be able to get away with passive cooling. However, you can always mount some 12V DC fan if you like. There are fan output pins on the D3806 that you can use. If you like this design, you can find it at Onshape where I use as my design platform.
