Walker Mount base

A mount for a Rollator/walker. The model I have at home can't use the universal mounts due to frame shape. This is the base im working off of to make custom accessories we cannot get ahold of anywhere else, so uploaded it here incase anyone else wishes to do the same.I use M4 screws and a nut to tighten it against the frame.Rollator/Walker Model: Mobilex leopard rollator Edit: Added Step files for editing
