This Ceiling Fan / Light pull chain knob, handle, finial, fob is designed for use with standard #6 (3.2mm) ball chain. It will also work with smaller chain as long as you use a #6 metal connector.
THIS ONE SHOULD PRINT WITHOUT SUPPORTS.
Simple feed the chain through the top of the print and attach a standard #6 connector to it. If using a ball chain and metal connector, you can form a loop around a keyring and hook with the other end of the connector.
If you don't have a metal connector, you can print the BALL-CONNECTOR.stl file I've included. NOTE: if you print the connector in PLA it's a tight fit. Lay the chain on a hard surface, position the connector over the last ball of the chain and push down until it snaps in place.
You may also use string with a large knot tied in the end.
I usually print things with 10% infill - HOWEVER, if used on a ceiling fan, you may want to use a higher infill for more weight.
I have designed hundreds of remixes. If you want to search by the type, visit my profile: https://www.thingiverse.com/ToaKamate/about
