Half grid Footfinity separate feet for Gridfinity

Footfinity, as seen here https://makerworld.com/en/models/1183739-footfinity-gridfinity-with-smaller-feet#profileId-1194389 is a concept to save filament and print time by separating the foot from the Gridfinity bin and printing it separately. I thought "Wouldn't it be great and save more filament if these were half grid sized? And the bins could be easily generated in any size easily?”What I found, ironically, is they don't save enough filament or time to justify printing bins with separate feet… Read on if you are intrigued. Design features include sample feet set with 5 sizes of studs that can be used to check the fitment of your printer and filament. The feet include a diagonal spur to maintain position so that it does not spin (automatically created in the generator).I have found with Bambu Lab white that the 6.6 mm diameter stud gives the best results while Sunlu white 6.4 diameter stud gives the best results. Make any size bin you like. Where?? Using the gridfinity b
