Update to my previous attempt at this, now supporting any number of stack levels via nesting handles.

Details

• 4x4 stackable Gridfinity frame (see: Zack Freedman's Gridfinity system)

• Includes a low-profile handle that allows you to pick up and move the upper row(s) of bins

• The handle nests in the bottom of additional copies of the frame, so you can now stack 'em as high as you want.

• Base has 1x1 feet that fit snugly into the rims of the lower row of bins

• Designed for __x__x3 bins (you could fit taller bins by increasing the height of the handle)

• Also rebuilt / cleaned the model mesh to improve quality when slicing (for example, old one had tons of sloped edges that approached infinity-small)

Printing tips:

• Printed this tons of times in PLA and PLA+ without any issues

• 0.20 - 0.24mm layer height is a good sweet spot for print time / quality in my experience

• In standard orientation, the bridges are small enough that you can probably get away with printing it without any supports (on a modern printer).

• That said, I like to add supports on the outer rim and in the hole where the handles nest (see my attached .3mf / .gcode for example of this)
