Wheel Chair Control Stick

These are wheel chair control sticks I made for a special little lady who was having difficulty steering her chair with the options available. They are designed to be used with a foot but they'll be perfectly suited for use by hand also. All versions are designed to go onto a 5mm stud. There are three widths that I'm uploading now but am happy to make changes upon request. The 4th version is the standard width but has the base stem removed for a lower profile mounting and will need a 5mm grub screw or other screw/bolt such as a cap head bolt to secure it down. This version hasn't been tested yet so feedback is very much welcome. I have added detailed drawlings of measurements in the photos but below are the widths, in millimeters, of the usable space between the uprights on the sides. Small - 100mmStandard - 115mmWide - 125mm Print with back side down. Supports are unneeded. PLA, ASA, ABS, & PETG have all been tested and work great. High infill is recommended to avoid weakn
