Lidfinity - Gridfinity lids

Lids for gridfinity bins held in place using Cantilever Snap Fit technology, made as a tool to turn ordinary Gridfinity bins into carriable containers with secure fit, tight clearance and stealth looks.

Features include:

• Four undercuts to allow opening on all corners
• Two tabs per side unit to provide secure fit

Made compatible with select versions of gridfinity catalogue, most notably:

• Fusion Gridfinity Generator (all bin types with lip but only in default 1.2mm thickness) (for example A1 hotend box)

• My collection of Simple Gridfinity boxes that were specifically altered to be compatible with the lids, regardless of thickness.

If you want to use with other bins, consult following schematic

I recommend printing in PETG (I used Zadar PETG light black).
