Permobil Unitrack Attachment Piece

This is the unitrack piece that can be used to attach to Permobil wheelchair unitrack system. I designed a cup holder and while doing so, realized that creating this piece to fit into the unitrack system was by far the most challenging. I have uploaded a STL, SHAPR, and STEP file to this so you can take it and add this to anything you'd like to attach to your wheelchair. The intent of this is to not print it directly but to open it in your design program of choice and then add something like a hook or cup holder, etc. to it to save you the time of designing the actual attachment piece.
