This is just a case made in FreeCAD for the Toradex Ixora Board. Although I modelled after the original .STEP file from Toradex, I did not include it in the FreeCAD file because it is their copyright, so it's better to keep separate. Hope you enjoy it, it has some detachable panels if you wish to use the GPIOs.
It is better to print with 0.2mm layer height because the dotted line for the detachable panels follow this pattern. You should also use some support on the larger holes. Other than that, it's pretty simple to print. I prefer PLA but you can also use ABS.
To lock the board into place you can use common 3mm screws, the smaller the better. I used M3/8mm.
