Hmm, I started to print and cut the cardboard, assembled it until become a helmet since my last post.
It means it took three hours, not bad!!
During my search of blue tape (which I can't find anywhere) I stumbled upon a "red tape". Only 5mm width and it only stated "strong pvc tape".
Okay, so I gave it a try. It actually quite strong, and very easy to do. It is a very thin PVC tape (not stretchable).
I am not sure how it holds during resin stage, but at least it holds now.
The down side is, it is very thin, so very flexible/wobly. I think I need several flaps with power glue to hold basic structure.
I ran out of power glue (again).
So the middle one is 188mm width, which is a keeper.
Still a bit tight, I think 190mm is better.
There are quite a huge gap on the top pf the faceplate, which I will add some cardboard later on
Also the lips not yet added, because I wanted to do flaps.
