I have solidworks if it becomes necessary.

I don't know how hot the lens gets, but with 3% power costing at 50Watt 1,5Watt would get converted to heat, but there is an air assist cooling, what do you think? (The lenses will arrive in a month)
I've used PETG for high pressure cones for a while. The only caveats are:
1. DO NOT let the beam hit the metal tip. It will heat up and melt the cone and disaster will ensue.
2. You might try plugging the output with your finger and see if the material walls are leaky. Sometimes 3D prints are not air-tight and air permeates through the walls. If that happens, a coating of spray paint will usually take care of it.
