Wall Plug Generator

About Wall Plug Generator

Wall Plug Generator prints plugs sized to your drill and screw: an expanding plug with slots, barbed fins and ribs for brick, concrete and stone, a screw-in plug for plasterboard turned in with a hex key, and a ribbed sleeve that repairs a stripped screw hole in wood. The bore follows the screw's core and your printer's fit test, and every plug prints standing, without supports.

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

Frequently asked questions

How much weight does a printed plug hold?
The tool gives no figure, because printed plugs are untested and depend on the wall, the hole and the print. Use them for light things only, never for shelves, overhead or anything that can hurt someone if it falls.
Which filament should I use?
PETG or nylon. PLA cracks as the plug spreads and creeps under a lasting load, and TPU is too soft to spread in a solid wall; the checks say so for your printer's filament.
Which screw fits which plug?
The usual ranges: a 5 mm plug takes 3 to 4 mm screws, 6 mm takes 4 to 5, 8 mm takes 4.5 to 6 and 10 mm takes 6 to 8. Drill the hole 10 mm deeper than the plug.
How does the plasterboard plug work?
Drill a 10 mm hole and turn the plug in with a 6 mm hex key: its coarse thread cuts into the board and its flange stops at the surface. Then drive the screw into it.
Do I need to install anything?
No. Wall 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.
