Anet A8 2040 V-Slot X Assembly

thingiverse

UPDATE 2017-05-26: I made a mistake by not providing dimensions for the 2040 extrusion. Here are the correct lengths: 475mm if you use the printed tensioner 490mm if you use the metal tensioner assembly These are minimum lengths. A 500mm piece from OpenBuilds would work fine as-is for both. I've uploaded pictures and a spec drawing of a metal tensioner assembly. It reduces the total width of the printer by 20-30mm. My prototype in the photos is shorter than the drawing because I had already cut the 2040 beam. You will need: Qty1 - 20x60x5mm Aluminum or steel stock (you can adjust these dimensions slightly) Qty1 eccentric spacer Qty1 idler pulley of your choice with a 5mm bore. The one in the photos is 20T. Qty1 5mm ID, 7mm OD shim Qty1 5mm washer or another shim Qty1 M5x25mm screw Qty2 M5 nuts Qty2 M5x10mm screws Qty2 M5 Tee nuts The Anet's stock X rail assembly is not rigid enough to support a direct extruder. I found Gavin's excellent 20x20 conversion, but already had OpenBuild 2040 V-Slot on hand, so I adapted. You will need his X-Carriage_Belt_Tensioner. https://www.thingiverse.com/thing:2088574 The Z limit switch mount is half of Kureigu's endstop Thing: https://www.thingiverse.com/thing:1443052 If you're keeping the stock extruder and hotend, you'll need a metal bracket for proper heat dissipation. The simplest solution uses OpenBuild's gantry plate and standard wheels. Drill the stock extruder bracket to fit the gantry plate. You will need: Qty1 - OB 80x20 gantry plate Qty4 - OB wheel kits Screw sets to attach the Anet extruder bracket to the gantry plate The Belt Clamp and Belt Clamp Plate Things. The Clamp Thing includes parts for both left and right side attachment, but you only need one. Or: The included gantry plate STL is designed to use a common steel right-angle NEMA17 bracket with the stock extruder parts. You will need: Qty4 - OpenBuild mini wheel kits Qty1 - This bracket (they're available everywhere, pick your vendor): https://smile.amazon.com/dp/B01HHPD7LY Qty1 - 22mm 3x0.50mm screw Qty2 - 25mm 3x0.50mm screws The FanMountPlate and FanMountBase Things to mount the part fan The X rails and lead screws are spaced 17mm center to center. This conversion should work on some Tronxy P802x models and any Prusa i3 clone with the same 17mm spacing. The Bowden conversion in the photos is a separate remix, which I'll publish eventually
