Custom coin keyring with text

thingiverse

This script is totally customizable to create your own keyring around a coin, and it will work for any coin or multiple coins. You can tweak the text settings like size and font to get exactly what you want. Once you run this script with OpenSCAD, it will tell you where to pause your print to insert the coin, then you can resume printing so the printer can enclose the coin perfectly. When measuring your coin, remember to allow some extra space for a perfect fit, and also consider a small vertical gap to avoid the nozzle from touching the metal of the coin. When you insert the coin, make sure it drops below the last printed layer, or else cancel the print right away to save your nozzle. For more details, check out the .scad file. An example STL is included for a 1x1€ euro coin. If you like this design, take a look at my other similar projects on Thingiverse: http://www.thingiverse.com/thing:1639203.
