Belt clip

For "Siemens Gigaset SL2 Professional"

Hard to print on my FFCP 2016.
I have tried 0.15mm layers only and not entirely successfully.
The SL2's has been replaced at work, so there will be no more updates.

A calibrated printer may be required for creating something usable; the clip contains minute details (the mini tabs) that need to fit the phone exactly.

New edition; "v2" might be easier to have stay *on* the phone.
New edition; "v3" even easier to have stay *on* the phone.

NOTE: This thing is thin (just over 2mm), Printing in ABS and Acetone-steaming it might be a very good idea.

Uploaded the FreeCAD files. These are very experimental and seems prone to crash FreeCad 0.16 under certain conditions - take heed!
