I was hired for design/printing of a piece that broke off of a motorized wheelchair. It was a bracket that held a neoprene bag for a cell phone.

The plastic didn't respond to superglue, nor epoxy. Unsure of what type, but was not ABS.

So I modeled it; took about 20 minutes, and ended up with the FreeCAD file and the STL. Printing took about an hour.

I charged $25 for total, with $20 for design and $5 for the part. And I offered future parts printed at the $5 price. They didn't want the design.

I found out the bracket, because it was for a wheelchair, was priced at $75. Just crazy..
