In Fusion 360 I sliced off the top of the bottle and formed a small box around it to be able to quickly 3D print a test case mold of just the upper neck. Two of these printed in about 3 hours, I cast plaster mold halves from them. Making a hole in the middle of the wire mounts was easy at the leather hard stage. The wire is 2.8mm dia, a 9/64 drill bit is 3.5mm. Simply twisting it to create a hole in the center of the pads takes seconds. Firing these to cone 6 enabled testing the fit for the swing assembly. I followed this with two more iterations to perfect the pad size and hole diameter (ended up at 11/64").
The link below links to a step-by-step in Fusion 360 of how to save a temporary copy of the mold drawing and modify it to isolate just the top portion of the neck.
