Geeetech single Z motor upgrade
Description
*** Update 200521: Please Check Out The Remix By Peppered: Https://Www.Thingiverse.Com/Thing:4377939 - It'S Awesome! *** *** Updated 181214: Added Stl For Nema 17 Stepper. *** *** Updated 180319: Added Files For Lower Z Guide Supports And The Filament Guide. *** ** Note: M@Rkd0Wn Works Whenever It Wants To. Sometimes It Looks Ok, Other Times Random Text Is Bold And In A Larger/Other Font. I Can'T Control This. ** This Design Accomplishes Three Things: - Keeps The Z-Axis Screws In Sync - Increases Available Torque (And Speed, Depending On Chosen Motor) - Provides An Easy Upgrade Path To Proper Lead Screws, Especially For The Common T8X8 It Is Designed For The Geeetch I3 Pro B, But I Suspect It Will Fit Others As Well. There Are Three Required Prints And A Few Optional. The Required Ones Are The Left And Right Top Z Mounts And A Brace For The Two Belt Idlers. Optional: Filament Guide And Lower Supports For The Z Axis Linear Guides. Things You'Ll Need Apart From The Printed Parts: 1 Bipolar Stepper Motor - Nema 17 Or Nema 23. 1 Gt2 852 Mm Belt, About $2 On [Ebay](Https://Www.Ebay.Com/Sch/I.Html?_From=R40&_Trksid=M570.L1313&_Nkw=Gt2+852&_Sacat=0). 1 Gt2 20T Pulley For Motor. 2 Gt2 60T Pulley With 8 Mm Id For Lead Screws. 2 Gt2 Ball Bearing Idlers With 5 Mm Id. I Didn'T Have That, So I Used Ball Raced Pulleys. 2 T8 Lead Screws, 300-400 Mm. 350 Mm Is Ideal. 2-4 608 Bearings (Od22/Id8/H7) 2 M5X30-35 Screws 3 M3X12 Screws Perhaps Some Other Screws, Nuts And Washers. Optional: 1 M8 Threaded Rod, Minimum 330 Mm (Used For Extra Bracing). 4 M8 Nuts And Washers. Don'T Be Afraid Of The Amount Of Text, This Is Really A Simple Upgrade.
