Step 2Prepare The Stensil
Each of the domes is made from eight (8) pieces of PETG plastic (similar to the plastic that drink bottles are made from).
The stensil is a two-stage straight-edge taper, with 1 cm tabs along both edges for joining the dome pieces together, except for the slot where the taper changes, so that the dome pieces can be bent at that point. You should also have a 1cm tab at the top and bottom for joining the dome walls to the top of the dome, and the skirt of the cone of silence, respectively.
I can't find the original one I used, but I have attached a PNG and PDF of one I just knocked up. YMMV.
I tried making a curved one that would make a truly hemispherical dome, but making a crease along a curved edge is beyond my ability. Besides, the two-stage dome actually looks pretty good anyway.
