Ender 3 belt driven z
thingiverse
This is a fairly simple belt driven z mod for the ender 3, pro, v2. I haven't tested it on any printer. I would advise printing the parts before buying anything just to make sure it fits. BOM 1x6mm od aluminum tube at least 100mm overall.(1x50mm and 1x28mm) 4x626zz bearings 6mm id 19mm od 1x80 tooth gt2 pulley 6mm id.(printed should work fine as well) 2x20 tooth gt2 pulley 6mm id.(again printed should be fine) 1x20 tooth gt2 pulley 5mm id. ^^^^ 1x20 tooth gt2 idler pulley 3mm id. 1x200mm close loop timing belt.(ninjaflex printed belts will work) I don't exactly know how long the timing belts that ride up the z axis will need to be but 2m should be enough. I designed it to use m3 t-nuts and square nuts.
