Dual Z & Frame Braces for Tevo Tornado and CR-10. Low cost high precision

thingiverse

I really liked the CR-10 Dual Z axis by Caster and Frame Braces from TomExplorador. So I decided to combine them and made some adjustments for the Tevo Tornado. To get an idea of the construction, please read the original posts and especially look at Caster's page https://myfordboy.blogspot.com/p/the-cr10-has-single-z-axis-leadscrew.html . You'll need the following additional parts: * 600mm leadscrew and nut: https://goo.gl/fM8znL * GT2 852mm Timing Belt: https://goo.gl/iXa4sv * 3 Bearings: https://goo.gl/HnzTqr (1 x idler, 2x right lead screw) * 2 x M8 threaded rods * 6 x M8 nuts * 7 x M5 x 20 screws (idler and lower holder) * 7 x M5 x 35 screws (upper holder and gantry plate) * 11 x M5 Tee nuts * 2 x M3 x 20 screws and nuts (bearing cover left) * 4 x M3 x 15 screws and nuts (lead screw nut) * 6 x M3 x 10 screws (pulleys) * 1 x M2.5 x 10 screw and nut (cuff (manschette8mm.stl)) * A few washers. You'll also need to print the following parts more than once: * 6 x BallNutM8 * 2 x 516_Nut (or 2 additional BalNutM8) * 2 x pulley-64 * 3 x Spacer8-7mm (for mounting the gantry plate) * 2 x Washer8 (right lead screw: between 64 tooth pulley and upper bearing and between cuff and lower ball-bearing) * 2 x Z-RHL-75 (right side upper & lower holder) For the left side, use the 100mm holder. For the right side, you can use either the 100mm or 75mm holder, but the 75mm parts are more rigid. I used PETG for the gantry plate because it's exposed to a lot of heat. If you don't want to dismount the right Z wagon from the X axis, do it without the inner gantry plate screw - the gantry plate mounting with the remaining screws should be strong enough. The Tevo Tornado extruder is higher than the CR-10 extruder. To avoid losing some mm of Z room, install the Tevo extruder turned 90° with the Titan_mount. I'm new to 3D printing and my CAD skills are limited. If you notice any flaws, please let me know so I can improve this thing.
