Adjustable Size End Cap, Bumper, Tip

I designed an end cap in which the size can be easily adjusted for just about any need. 2 example STL files are included: one for mini foosball table end caps opposite the handles and the other for doorstop bumper tips.

Open the .scad file in OpenSCAD and you can edit the top and bottom outer widths, the height and the inner diameter to fit your needs. Save and export to STL.
