This is a small project for a lasercut enclosure for this 12V/60W switching PSU from Aliexpress which is also available from many other vendors. The whole thing is done in FreeCAD so anyone can take a look.
The idea was originally to 3D-print the case, but I recently gained access to a lasercutter, so I decided to go down that route. The case_simple variant is just the walls of the 3D enclosure with the corresponding holes whereas the *_cut variant has tabs added with the LCInterlocking workbench. The *.svg files are then used for cutting.
Parts used:
Instead of measuring and parameterizing the model myself I decided to look for the models on grabcad.com and base all cuts on them. I used the following models in the design process which can also be found in the 3d_models folder:
- S-60-12 PSU Model by Aleksander Ugnenko
- IEC320_AC-14 Power Connector Model by Richard Bruning (currently not used)
- IEC320_AC-17 Power Connector Model by Igor Vladimirovich
- DC_Jack_5.5mm/2.1mm Model by Yannik Fink
The side pieces should just slide together, depending a bit on the kerf of your laser (0.2mm was fine for me). This can be configured with the LCInterlocking workbench. The two parts of the top lid are simply glued together as well and held in place by very small magnets that I drilled small holes for, though the lid already holds by itself if the right kerf is chosen.
