Permobil Powerchair Unitrack Rail Phone Holder

RAM Mount Makes a Great Phone Holder for the Per Mobile Power Chair. Unfortunately, You Have to Go Through a Dealer to Get It, But I Found a Workaround. I ordered some individual parts from Amazon and mounted them to my custom-designed holder using the RAM mount as a base. The only issue that's been bugging me is the ball that screws into the mount has a tendency to spin when you're on uneven terrain. Adding a few washers against the plastic helps keep it in place, but I'm still looking for a more permanent solution. Edit: I've come up with two new designs that address this issue and improve overall stability. Design V2 features holes to secure the mount to the chair rail using M6 bolts, which provides added stability. The main hole is now sized for a 1/4 threaded insert to prevent the ball from spinning. I've also designed a new mount with the ball built in, featuring a "perimeter" design that increases strength and stability. By making the ball's perimeter layers thicker, I was able to make it extremely strong and resistant to spinning.
