Remixed Tubular Keyboard Stand by karnlund to be a bracket for a quick disconnect Loc-Line switch mount for a wheelchair. The bracket stays on the wheelchair when the student leaves for the day and quickly re-connects the switch for an augmentative communication device the next morning.
Used 2" x 1/4" bolts and 1/4" nuts inside the wingnuts. Pause your print of the wingnuts and drop in the 1/4 nut before the print continues to print the top of the wingnut. Approximately 6mm.
3/4" Loc-Line will snap onto the Loc-Line End and which ever plate you print.
The scad file can be used to customize the bracket for the size of the tubular steel of the wheelchair. Use the scad file to make one bracket with hex head insets and one without.
Then use Tinkercade to inset the "Cube" onto one of the brackets.
