Gridfinity

Gridfinity is a free and open source modular storage concept published by YouTuber Zach Freedman. ^{launch video}

It is based on a 42 × 42 mm grid that can turn any flat surface (e.g. a drawer bottom) into a solid foundation for custom 3D printed containers.

Printing Experience

• baseplates: gridfinitygenerator.com/baseplate
  • select "connectable" for easy linking with 3D printed clips or "screw holes" if you have the option to screw them down
  • Bambu Labs P1S (P7 or P8), PLA @ 0.28 mm layers
  • color does NOT matter, use up scraps!
• connection clips: gridfinitygenerator.com/connection-clip
  • tolerance set to "0"
  • Prusa i3 MK3S+ (P9), PLA @ 0.2 mm layers

Drilling Table Drawers

In progress (#363)

Available Space

The main drawers on the drilling table (as of 2026-9) have the following inside dimensions:

• depth: 68.4 cm
• width: 33 cm
• height: 10.2 cm

In other words, they can be filled with up to 7x16 Gridfinity units at a height of max. 10 cm (including contents!)

Printed Parts

These (and perhaps more) elements are used in the drilling table drawers:

• Stackable Forstner Drill Bit Holder
• Slotfinity (modular tooling tray system for storing oblong parts)
  • white dividers labeled with permanent marker
  • 1U for twist drill bits up to approx. xxx mm
