Dining chair plug

This hand-me-down dining setting was missing half the plugs that covered the screw holes. Many of the others were loose and 5 year olds love to touch things until they break.

This is one of the first models I made with build123d.   I've uploaded 3 different tolerances since it's great to have one that's easy to get in but hard for a child to get out.

I printed it at 0.12mm in eSun light brown PLA (a bit too light for my chairs but probably better than too dark).

The step files are generated with 12.5mm, 12.6mm and 12.7mm diameter bases.  You won't need supports if your printer can do a 75 degree overhang.
