A case for your Tatacon to USB Converter, obtained here.
If your converter came with a case, it is V5. Otherwise, use the V4 files.
Early revisions of the V5 had a 1.6mm PCB. Later revisions use a 0.8mm PCB. For these later revisions, use the V5_Thin files.
It's quite a tight fit - you might need to modify the 'fat' and 'fudge' parameters if your printer tolerances aren't great. 'fat' makes the PCB width bigger, 'fudge' makes everything looser.
Nozzle size: 0.4mm. 0.2/0.1mm is also fine.
Designed to print small side facing down for the main case, clips touching the bed for the rear cover.
