>>6840521>>6840506>>6840521These guys all have much softer heads, so you can get away with a less exact (smaller) hole and they'll still fit really good.
Any specific questions, let me know and I'll do my best to answer them. Again, do a practice run on something first! It's easy to go at a wrong angle or to put the hole off center if you're not paying attention.
>>6840517If you don't like feeling like you're in a shitty crack den by heating up household items with a lighter, I suppose that would work!
>>6840459Fuck yeah! I was probably inspired by yours in the first place. Love how they scale with Transformers.
