I've been trying (and failing) to make a 3D model of a layer that's compatible with Hasbro tips instead of TT, but I've run into the issue of the slopes. I don't know how they interact with the tip obviously since they're fully enclosed by the layer 'till the thing bursts, and the individual differences between layers aren't as prominent or obvious as the teeth on TT layers.That said, are there any diagrams or schematics for a "basic" Hasbro layer that has measurements for how things should fit?

You could take apart a Spryzen Requiem/Legend Spryzen and work with the separate slope piece.
