First of all, a big thanks to Zack Freedman for opening this "Pandora's Box" to the world! Here is my remix and optimization for the basic frames. I noticed some notches on the last few layers of the original frames which caused inconsistencies. I trimmed the top off to be a minimum of 0.5mm so that most printer nozzles can print it easily. Also I trimmed the bottom chamfer to save on some filament and time.

Enjoy and happy printing! Stay tuned for more optimized Gridfinity stuff:)
