This is a housing for a benchtop power supply using the "MingHe B3606" CC/CV module. There are several variants of this module, this is for the 36V/3A 50x66mm veion.
It utilizes a Sieme SITOP PSU100S DIN Rail Power Supply as a DC source.
And yes, if you have to buy the Sieme supply new this build is not really economically viable. But as these are often available used on ebay for a reasonable price this might still be interesting for some.
Other DIN supplies might fit as well. The dimeio of the used supply are: 70x126x126 mm.
There are three through holes for binding posts. I decided to use the 3rd to lead out the unregulated 24V/10A from the Sieme supply. Alternatively this position could be used for PE.
If you buy the design here the Fusion360 source files are included in the download.
Printing
The printing should be straight forward. Support is required at least for the front cutouts of the module as these need to be quite precise.
The feet are ideally printed with TPU. An alternative that provides very good grip, is to cut fitting pieces of silicone rubber hose and press them in.
The light-guides for the modules LEDs are not strictly necessary but make them less directional. Print with traparent PLA or tralucent white.
For the raised lettering on the butto I switched materials from black to grey during printing.
Materials
In addition to the printed pieces you will need:
Three iulated binding posts.
A switched and fused IEC socket and two screws to mount it.
Two short M3 screws to fix the power supply module with the supplied frame to the housing. The screws that come with the module should work for this.
Cabling.
