Jump-start your rack design:
Drill bit organizers, pen holders, paint brush racks, makeup brush stands, spice vial holders, electronic component storage. Anything cylindrical that needs organizing.
Gridfinity style locks into a baseplate and stays put. Minimal hex style is lighter, prints faster, and works standalone. Choose Gridfinity if you have a baseplate system; choose minimal for desk use.
No — the holes are fixed size. Measure your items first and add 0.5–1mm clearance. The parametric generator lets you dial in the exact diameter before printing.
The generator automatically calculates minimum wall spacing based on your tube count and grid size. Choose a larger grid if tubes feel too tight.
