Build log HyperCube 3d printer - part 1

I ordered the first parts of my new 3d printer, 4 meters of 2020 profile. That is for the outer construction of the printer, that is the first part that I will build.

Have already printed some(9pcs) of the corner parts to connect the 2020 profiles.

DIY - Power suppy CV / CC

I'm working on an enclosure for a cheap eBay CV/CC power supply. I use ThinkerPad for designing the enclosure, have not much experience with 3dd cad software so I choose beginners friendly one. This is the test version, used only 0.5mm thick walls, 1.5m PLA = $0.11, that is very cheap for the prototype model. 😄 If the enclosure is ready I will post it online.
