Customisable Parametric Clog Charm

Different brands of clogs have different sized holes and thicknesses, and even different sized holes on one clog. I designed this so I could get a snug fit in different clogs and holes. Emboss, embed or engrave text or emojis on clog charms. Choose between a round charm for an emoji or a rectangular charm for text and/or emojis. Make multiple round charms with different letters to spell out words with groups of charms.

The embedded option will give a charm face that looks flush but retains text/emoji edges and is easily painted in your slicer using the "fill" and "detect edges" options. The engraved option will cut into the charm top, and the embossed option will add the design as a raised design on top of the charm cap.

Defaults will fit many standard style clogs but you're able to change the parameters to suit your own clog, or size it for a buttonhole or brooch pin hole etc. The inside clip diameter will automatically resize as you change the hole diameter, but it is also individually adjustable for more or less width.

Charms are rendered top up, but the embed option would benefit from flipping face down before slicing for print, and the engrave option depending on the bridge width.

Sections are colour coded on screen for easy part identification but not saved that way in STL exports.
