Ergotopia Masterback headrest extender

This is an adapter for the Ergotopia Masterback to move its headrest further back. Ever since i got this chair i felt like the headrest leaning forward way too much so i designed this adapter.

I printed it in PETG with 4 walls, 25% infill. PLA is probably strong enough. I the original Torx-screws and 2 random wood screws that are about similar in size.
