Silent keychain
prusaprinters
<p>If you hate noisy bulky keys as much as I do then this design is for you.</p> <h3>Print instructions</h3><p>To assemble the keychain you will need:</p> <ul> <li>2 pcs M5 screws </li> <li>2 pcs M5 nyloc nuts </li> <li>some O rings with 5 mm inner diameter between the keys<br/> Update #201700503: based on Mark's comment I have added an iterated version which can be used with binding posts instead of M5 nuts & bolts. You can order the compatible threaded posts here: <a href="https://www.banggood.com/4-15mm-Screwback-Button-Stud-Screw-Brass-Nail-Leather-Belt-Chicago-Rivet-p-1003876.html?rmmds=myorder">https://www.banggood.com/4-15mm-Screwback-Button-Stud-Screw-Brass-Nail-Leather-Belt-Chicago-Rivet-p-1003876.html?rmmds=myorder</a></li> </ul>
