Parametric Easy Screw Top Container Maker, FreeCAD Generator

Cylindrical storage made easy. Create your own screw top container. Use them to store anything: Screws, washers, coins, pills, jewelry, batteries, whatever.

No proprietary software required. That means no Fusion license, no Solidworks license, no BS. No need to stare at OpenSCAD code either. No math. No fiddling with thread clearances. No supports required. No fuss. All these “no's” add up to: Yes!

All you need is a copy of FreeCAD.

This Version Is Improved Over the Original:

• Grip knurling is added to the cap.
• Improvements to thread clearances.

Just define the height and diameter you need in the included “Parameters” spreadsheet and the parametric functions do the rest. Dimensions are specified by inner height and inner diameter, so you only need to know the dimensions of your desired object(s) to store. Thread beefiness is proportional to the wall thickness. You'll get a working thread interface every single time. Just export both parts and print.

Note: Generated containers are not guaranteed to be fully waterproof unless you add a gasket.

Print both parts open end up on your build plate.
