I had made a couple mini power pod firewalls using FreeCAD. I made them with the typical 16x19 or 12x16 hole spacings. Now that motors are coming out with all kinds of spacings (16x16, 12x12, etc.), I thought it would be a perfect opportunity to play with OpenSCAD and the Customizer App on Thingiverse. Users can now either download an STL file of my original "standard" firewalls, or click the "Open in Customizer" link and specify their own parameters for just about everything. Check it out below!
