A 1x3x10U gridfinity bin with:

• 1 - 34 x 88 mm slot for a Wiha screwdriver tin of the type shown in the photos
• 1 - 12 mm round slot for a "4 mm PicoFinish ESD micro bit handle" or other similar handle
• 1 - 5 mm round slot for a “4 mm magnetic micro bit extension”
• 3 - 4.5 mm (edge-to-edge) hex slots for 4 mm “micro bits”
• Corner magnets with removal slots
• Stacking lip

Tolerances work for me, but you may need to calibrate your machine and/or filament settings for a proper fit.
