Wheelchair Mounting bracket

I made this due to someone needing a mount for an AAC device to her wheelchair. It does rely on clamping force so its printed fairly thick. There is a slight grove in the middle if you needed to add a strip of rubber/foam to increase friction on the bar of the wheelchair. Step file is included if you need to adjust it at all. If you need another file type just let me know. Boost MeIt uses 4M screws and nuts to clamp with. mine at 60mm long but I think they can be a bit shorter.
