Drywall countersunk screw washer #6 size bugle head
Most countersunk washers are a true 40 or 45% bevel, this doesn't match a standard bugle head drywall screw, so I made this.
I recommend to print with 3 walls
There is a "flatter RARE" model, I would only print that if you need it, the other file should fit.
Original onshape model in case you need to edit
The author marked this model as their own original creation.
