Description
A good as possible (imo) replica of the old PSU-box for the Commodore 64 and VIC-20.You can use it to built in your psu-replacement.
The outside is a precise replica of the original, the inside is cleaned out to give you space for your own electronics.
The bottom is there in two versions, as close as possible to the original and a flattened version for easier printing (see print-settings)
The top and bottom are connected with 3 M3-screws or self-tapping screws (be sure the screw-holes are big enough).
You can use the original rubber strain-reliefs or use the included cable-inserts.
Read the print settings for more information.
Happy Retro-computing:)
PS. Sorry for the photo-quality, but red is apparently not an ideal color for my phone. Believe me it looks very nice.

Jupiler PLA, but PETG is probably better
Notes:
Printing-tips:
Top: I got really good results with Cura 4.1.0 and the now experimental "conical support" and "adaptive layers" settings.The screwholes are 2.4 mm in diameterand you have to threat(?) it for m3 screws. Self tapping screws is also an option.
It is a long print, it took me 15-20 hours on different machines.
Bottom: The easy printable version can be printed flat on the bed. The one with the "ring-feet" is not so easy to print due to the needed support. A solution that worked reasonably well is to rotate that bottom-part 45 degrees over the long side. Together with minimal support you got a nice result (see picture). Downside to this is the almost trippled printing-time.
The screwholes in the bottom must be cleaned, there is a thin layer in the screw-holes to ensure a good finish.
Cable-inserts: these are a tight fit, fit them first before using them.
