DanaR-Insulin-Pump-Armholder

I printed the case for the arm with a layer thickness of 0.1 mm (fine) with the Ultimaker Cura Software and my WANHAO Duplicator i3 Plus in PLA filament.

The housing has plenty of space for the pump, the pin for closing keeps the pump stable in the housing.

For wich insulin pump is this armholder?
* DanaR

Why so much space for the pump?
* That there are no unnecessary scratches :)

How is the pump attached to the arm?
* With a 24 cm wide elastic waistband
