Hospital Bed Leg Lock
I really don't know if anyone else is going to have a use for this item and I originally had no plans to upload it to Thingiverse. However, after thinking about it a few days I decided to go ahead and uploaded it, just in case someone has run into the problem I did.
Simply it a small block that keeps the hospital bed I have been forced to use from sliding across the floor. Keep in mind that it will require you to screw the block to the floor.
