MINI ITX TERMINAL FALLOUT – CALLISTO 2 (V21)
UPDATE- NEW VERSION FIX SOME ISSUES V26 VERSION
power button easier to install, keyboard fits but still clashes on the sideways, power supply cable fits easier.
I recommend the version named V26_PARTS_callisto_2_montado_3mf
The history photos on thingverse shows the start to end/ follow up of the project
USE A RUBBER HAMMER TO MAKE THE PINS FIT ! DO NOT USE A METAL HAMMER IT CAN DAMAGE THE PARTS PRINTED
i used 60% infill in the 10 support pins that hold the parts, and i always hold the pc with my hand below in the middle since im not sure if the pins wil hold the weight if i hold only in the front. i just dont like to risk it
Dont forget to check the screen size if it will fit with yours, i put a square to reduce the screen area above. you can remove it.
I had some spare parts from an old pc and love fallout franchise so i decided to make a callisto 2 windows pc.
