A 3d printable top case for the Atari STFM, it comes in two variants. The first variant is an all in one (ish) that can be printed an large format printers or professional print houses, the long standoffs at the rear are still separate (you need four) as they have a tendency to break so these can be printed with a higher infill, in a stronger material or even just a few extras.

 

The second variant is split into 5 parts which I printed on my Ender 3 V2, I did a 20% infill for the body and 80% for the rear standoffs all out of PLA, I used 1mm wire for the joins and I cleaned out the holes with a 1mm drill bit (by hand) before inserting them (https://www.aliexpress.com/item/1005002726975759.html) I also purchased some led diffuser acrylic and cut it to fit neatly in the case (https://www.aliexpress.com/item/1005002538503598.html). The screw holes I cleaned out with a 2.5mm drill bit (by hand) and used the original case screws to cut a thread before assembly.

 

The standoffs are attached to the main body of the print with 4 off M3 x 16mm hex head bolts and nuts. The nut is inserted into the standoff and the bolt slides onto that main body and srcewed together. I just did them up finger tight. 

 

I have not printed the all in one and it's just a fused together version of the 5 part variant so I have no idea if it works.

 

The icons for floppy access and eject are just blanks because there's no way to get the detail with a FDM print and I plan to print a custom clear label.
