Geeetech i3 plywood printer Z axis connection

thingiverse

The Geeetech i3 printer has a tendency to lose sync with its 2 Z axis steppers, so I've attempted to gang them together here.\r\nI used a G2GT-852 belt, along with two 20 teeth idlers featuring a ball race with a 3mm hole, and the driving pulleys are two 40 teeth pieces with an 8mm shaft hole.\r\n\r\nThese adjusters keep tension on the belt while also holding it close to the frame.\r\n\r\nNOTE: A modified version2 set has been added. I haven't created these myself but they should provide a bit more clearance between the belt and the frame.\r\n\r\nFiles are available at...\r\n\r\nhttps://www.tinkercad.com/things/gGFSCjT6vx4-geeetechi3topzbelt\r\n\r\nI'm planning to add top bearings, in fact, they're printing right now.\r\nhttps://www.thingiverse.com/thing:1776244\r\nThanks go out to https://www.thingiverse.com/shawdreamer\r\nAn updated picture will be posted when that's done.\r\nEDIT: They didn't fit this machine so I came up with my own version. There are plenty available but I decided to give it a try myself.\r\nhttps://www.tinkercad.com/things/5aypFj0Bold-geeetechzbearingholder/edit\r\n\r\nIt appears my printer is not entirely accurate in its print size, so I had to tweak them slightly. The bearing holder needs to be flipped horizontally in the slicer for the other side.\r\n\r\nThe next modification on my list is the BL-Touch. https://www.antclabs.com/bltouch
