Stronger Extender for Handy 2

An altered version of the official Handy 2 extender making it easier to print on an fdm printer. I basically thickened the interface part facing the user with 1mm. The result is that breakage is less likely.
The internal ribs were also removed as they only add to material and printing time.

Printing

The downloaded file is pre-orientated and should load with supports. Printing it diagonally gave the balance between strength and finish. Printing it flat is no problem either. However, the areas where the extender clicks on the Handy 2 seem to separate more easily.

Please let me know what you think of it!
