anet a8 Yaxes Linear Bearing

thingiverse

Simply ditching heavy aluminum cufflinks and metal bearings. Already proven that PLA bearings are a resounding success after several years of use, the metal bearings are beginning to wear out and produce a scratchy noise. Replacements are astronomically expensive, so why not just print one instead? You might think that the bed takes a lot of loads, but it only needs to be smooth for the Y axes - nothing more. Old ones for Anet A8 use 4 bearings with 16 screws. None of them use 2 bearings with 8 screws. One-piece linear bearing. You'll need spacers or washers for v1 and at least 20mm screws. The reason is that it's too low for an Anet A8 and crashes the bed on the backplate. DO NOT OVERTIGHTEN, if you fasten it too well it won't be a smooth run, similar to the stock bearings. The print setting is straightforward: 0.4 nozzle 2 wall thickness 70mm/s speed 0.15 layer height 5 lines brim Enable retraction Infill 15% only trihex 0.6 nozzle 1 wall layer 85mm/s 0.3 layer height 5 lines brim Disable retraction Flow 110% 40% infill gyro Don't overdo it, you don't need much material, the brushes on V3 are only 0.8mm thick 2 walls, and it works just fine. The new v4 is improved and easy to print - 0.6 nozzle, 1 hour each, slip-in nuts and short screws.
