For my astronimic equipment - specifically the AZ/EQ-6 mount, which was very uncomfortable to carry for outdoor observation - I wanted (for years now) a exclusive selfmade bag. So I began CAD modeling:

This is the DXF result of modeling.

Later in the production process the outlines were cutted out of parachute tarpaulin and sewed together. After that a custom screen print was made. Here are some impressions of the finished bag:
