Thought I would make the Splines update a separate post.
I've come up with the dimensions for an initial set. I just benchmarked what is currently offered.
My thinking is an initial set of (8) splines with these dimensions:

They would be made from HDPE (same material plastic filler spreaders are made of) and cut with square edges and corners.
These are so simple, I'm not sure the cost of typical prototyping is justified.
I'm thinking to do a "Prototype Pre-Sale" where I just place an order for those who want to give these a try, understanding that they may not be the final end product, but are probably very close.
Cost, with shipping included, would be between $50 and $75.
Any interest? I'd need about 100 sets to make the factory run and inbound shipping worthwhile.
