I tend to find that it is really useful to divide some shapes into quarters so I can put them back together exactly as I want them, but all the blueprints I used before were large and kinda uggo. So I endeavored to make as small as possible a blueprint which could cut shapes into quarters no matter what the shape was.
I call it a "Universal" quarterizer (yes I like that term) because it is input agnostic. you can put any shape into the input and it will output quarter shapes with each quarter getting their own belt (no belt mixing). The outputted shapes will always be north western quarters. (that made it a pain to fit into a 1x2 platform but I felt it was a necessary component.) 1 belt total of input results in 4 belts total of output (depending on the input shape).
Oh and I haven't reached crystals yet but I don't think it's compatible with them.
