Plug Generator – Parametric Caps, Plugs & Inserts

Looking to close, cover, or plug something? Look no further. PlugGenerator is a fully parametric OpenSCAD generator for end caps, hole plugs, insert plugs, and protective covers. Measure the outside of an object for a cap, or measure an opening for a plug, then choose the shape, fit, retention, and construction settings you need.   A shared sizing system keeps the workflow simple, while flexible fit, retention, and finishing controls help you shape the result around your exact use case.   Click Customize to open the generator. 🚀 Quick Start 1. Choose the Closure Select Cap to fit over an object or Plug to fit inside an opening.   2. Enter the Shape and Size Choose Round or Rectangle, then enter the measured width and length. Matching values create a circle or square.   3. Adjust the Fit Set the body length, clearance, taper, and entry style. Add ribs or barbs when extra grip is needed.   4. Customize the Design Choose the plug construction, slots, and end style.   5. Preview and Export Once you’re happy with the result, export your model at the desired quality. ⭐ Features All-in-one Generator Create end caps, hole plugs, inserts, and more in one simple workflow.
