Hole Plug Generator

About Hole Plug Generator

Hole Plug Generator closes holes: snap-in plugs that hold panels across a range of thicknesses, ribbed plugs for blind holes and the open ends of round and square tubes, and desk grommets with a cap and a slot for the cables. The stem takes your printer's measured fit, the legs are sized to bend as little as the panel allows, and every plug prints head down without supports.

The full guide: every step with pictures, examples, print settings, fixes and every setting.

Frequently asked questions

Why do plug legs snap, and how does this tool help?
Short legs bend far as they pass the hole, and layers printed upright split easily. The tool sizes the legs from the bend your filament takes and warns when a thin panel leaves them too short; PETG or nylon spring back better than PLA.
My plug keeps falling out. What should I change?
Set the panel's real thinnest and thickest thickness: one sloped barb pulls the head tight on any panel between them. For a blind hole or a tube, more rib grip makes it hold harder.
Which hole sizes do desk grommets use?
60 and 80 mm are the most common, cut with a hole saw. The tool names the nearest hole saw for the hole you set.
Can it cap square tubes?
Yes. Choose Tube end and Square, then the tube's outside and wall: the plug fills the inside and its head covers the end.
Do I need to install anything?
No. Hole Plug Generator runs in the browser, and the geometry is built on your computer. It is free; you need a free NabiMakes account to download the files.
