Power supply case

Powersupply case for laboratory powersupply made of "china" parts. In my case its 0-32V 5A with bluetooth support (android app).

There is stl Powersuppply_case_complete_do_not_print.stl - it is only for full overview of the case - do not print this file ;-)

I printed it with some unbranded brown PLA and it came out like "vintage" box. So i call it vintage powerbox, maybe the rounded corners did this vintage look :-)

Print Settings

Printer Brand: Creality

Printer: CR-10

Rafts: No

Supports: No

Resolution: 0.25

Infill: 15

Filament: Gembird PLA Brown
Notes:

Holes in shell for components are "big", so you should print with supports - but in my case bridging works fine so i printed it without supports.

Post-Printing

Just some filing/deburring. The shell part warps a lot but it is not a problem at all. You should try to print upside down with lot of supports maybe with better result.

To mount components use some spare screws - holes are 3mm diameter.

How I Designed This

Measured components and tinkered in tinkercad

List of electronic components to build same power supply. There are more versions of boards, so if you choose different then i do, holes or dimensions should vary!

Android app

Buck converter (the front display part) which i ordered came with bluetooth module. It works with this android app. Pairing pin was 1234.

Wiring components

Wiring diagram not included - it is simple as F. But if someone needs that, i will upload some schematic how to connect all the parts.

There are mains! I'm not responsible for any injures if you try to build same device and you don't know what you are doing!
