ASCI2STM Atari ST hard drive emulator enclosure

"This enclosure is for the ACS12STM SidecarTridge “Castillian” Revision 2.x produced by Diego Parrilla in early 2025. This version has sprung SD slots and improved circuitry. See https://sidecartridge.com › products › acsi2stm-atari-st

This enclosure is in 2 parts with separate stl files: Top (Battery side with DB19 slot) and Bottom (with mounting holes).

To join the halves use 6 x M2 8mm countersunk wood screws, optionally you can use hot glue like me :)

The Top has an optional 39mmx5mmx1mm spacer so that enclosure sits vertical against the rear of the Atari ST. This should be glued onto the enclosure at the bottom, this is not inluded in the print profile but  you can find it in the “ACSI2STM_SidecarTridge_Top_v1.3.stl”. I haven't included it in the print profile because it's optional. also the parts in the print profile is 2 percent wider to accommodte some versions of the cartridge.
