I want to vent my H2D’s rear exhaust outside and while looking at the available adapters on Makerworld I went to see what type of heads the vent opening screws have.
Two issues:
The back panel partially covers the screw heads; do I need to remove the entire panel to get to them?
After getting no grip with 1.0, 2.0 and 2.5mm Allen wrenches (the 2.5 won’t go in the hole), I looked more closely and saw that the recesses in the screw heads are cylindrical (see photo)!
As shown in the photo, it’s the H2D back panel where you can see the lower right corner (left if viewed from the front of the machine) of the louvered vent.
