Shower Door Soap Dish

Here's another soap dish. But this one fits between a shower door and bar handle. All parts snap together for easy assembly/disassembly. The bracket/clamp part can be mirrored as in CURA, etc. The only variables are the bar diameter and the distance between the bar and door. In this case the bar diameter is 19 mm and the bar-to-door distance is 52.5 mm. My goal is set these two variable is in OpenSCAD to make this design applicable to any shower door/bar combination. Comments welcome.
