The gridfinity base plate is 5x5 and 220x220mm it takes ~6hrs to print and uses ~140g of filament. The baseplate was modeled after Mcbillsan's Snapfinity baseplate. The drawer system is 220x53x216mm it takes ~12hrs and 17mins and uses ~600g of filament. 

Print all parts of the drawer system upright and together.

Print the baseplate with supports.
Print everything using support cubic.

Use the drawerfinity 2.0 I recently made instead
