Customizable Hole Plug Press-Fit Cap with Flange

A clean, parametric flanged hole cover cap designed to blank off an existing hole with a neat front face and a secure insert. This model is perfect for panels, enclosures, printed parts, ducts, and general openings where you want a simple, professional-looking cover.

The cap uses a solid front flange to hide rough edges and provide a finished appearance, plus a press-in spigot to center and hold the part in place. Choose your preferred retention style in the Customizer:

- Retention Ribs : subtle rib features for a gentle interference fit (great for printed holes and repeated removal). - Barbed : stronger one-way style retention using barbed rings for a more aggressive hold. - None : plain spigot for a slip fit or glue-in use. All key dimensions are adjustable (flange diameter, insert diameter/length, wall thickness, and fit clearance), so you can dial in the exact fit for your material and printer tolerances.

Printing tips

- Print flat on the flange for best surface quality and strength. - For press-fit results, tune fit_clearance to match your hole accuracy and material (PLA/PETG/ABS). - A small tip chamfer helps start the insertion cleanly, especially with barbed fits. Typical uses: enclosure/panel hole cover, blanking plug, dust cover, knockout hole cap, finishing ring + plug, grommet alternative .
