PC Test Bench

I like to build computers but sometimes its difficult to test everything on top of a box.
So I made a Test bench With 3D-printed parts.

I used 2 rectangular pieces of multiplex and put the wholes (7mm) the right measurement which u also can find in the pictures.

Than u can put the "Pin" inside.

Second u have the "Gaficsupp" for the support of the Graphics card. (only item that needs support)

Third U will need the "PSU Mount" for the power supply ATX formfactor. Normally this is a friction fit but u can use a screw for more stability.

Last u can use the "Support" this is for making space between the PSU and the motherboard. This I designed in a few different forms.
U have 3 possibilities:

3x Support 1 + 1x Support 2
3x Support 3 + 1x Support 4
3x Support 5 + 1x Support 6
Or u can even mix
The 2,4 or 6 are at least 1 time needed so u wont intervene with the "Gaficsupp".

I designed this for my own use but if people like the design and want to build this themselv
