<p>The following is for a bicycle mounted enclosure for the SCK2.1 sensor.</p><p>https://smartcitizen.me/</p><p>The sensor case is easily detachable from the bike mount.</p><p>&nbsp;</p><p>Make sure to orient the parts as necessary for your printer.</p><p>&nbsp;</p><p>Instructions in 3 parts:</p><ol><li>The supports<ol><li>Use spacers to hold the SCK boards</li><li>Print the GPS support arm to mount the GPS to the main SCK2.1 board stack</li><li>You need two PM-MB holder prints to hold the PM sensor to the main board</li><li>Pay attention to the orientation of the PM sensor in regards to getting the cables to stay as flat as possible.</li></ol></li><li>The enclosure<ol><li>It's a big print (5-6 hours) - print “standing up”</li><li>Print the lid</li><li>Put the lid upside down on wax paper - with a hot glue gun create a dome of glue and let cool. This make it easy to see the LED light.</li></ol></li><li>The bike mount<ol><li>Print both parts</li><li>Use two M3 nuts and bolts (16mm) to mount</li><li>I crazy glue a bit of inner tube to the mounts curvature where the handlebars will come in contact.</li><li>Make sure the quick-release clip is towards the rider.</li><li>Don't pull on the quick-release, squeeze.</li></ol></li><li>Final steps<ol><li>There's some rattling.</li><li>I use two types/densities of foam strips to provide friction between the SCK and and case, as well as to hold the batter in place.</li><li>Due to shaking the SD card sometimes pops out - but is still in contact. This however makes sensor removal from the case a bit delicate.</li></ol></li></ol><p>My plan is to design a similar case that integrates the case and supports as one print - preventing rattling, the need for foam, and SD card problems.</p>
