Gridfinity base for the 52" height-adjustable Husky workbench. There are 4 plates, and each one needs to be printed separately since they're big. The “middle” pieces need 3 of each and the “corner” pieces need 2 of each, for a total of 10 plates of printing. You'll end up using a little under a half a kilogram of filament for all of this.

Also, there is a small gap around the sides of the inserts that I found necessary to account for slight bends in the sheet metal and some protruding fasteners. Once you load it up it shouldn't move.

I used this base to hold Troy's lathe tools- https://makerworld.com/en/models/1111762#profileId-1108453

FYI, the current version of those lathe tool holders doesn't fit fully in the top drawer due to a bar going across the inside (part of the height-adjustment mechanism I think). It will fit fine in the bottom drawer, or you could just put the lathe tools in the front-most 5 slots.
