|Black Pentimo with no dividers (rendered)|
I am pleased with the appearance of the 'refined' tiles. The pips are sized and arranged so that the dividers were unnecessary, and removing them makes sense.
Unfortunately, removing the dividers did not significantly lower cost (just a few cents per tile). It turns out that laser etching is a fairly affordable process relative to thru-cutting. With 104 tiles and the assorted chad created by so many 'irregular' cuts, there isn't much to be done to minimize cost on the making front. I could remove the center hole and trim around 5-10% of the cuts and cost, but I consider the hole a critical part of the design; several of my game concepts for Pentimoes actually need a thru-hole.
For now, I am going to maintain both versions and choose one when I am ready to drop the dime.
