Prusa i3 Leadscrew, Bearing, ZStop, Belt tension upgrade
Description
This Is An Upgrade Design For My Reprap Prusa I3. It Includes X Motor And Idler End Replacements To Make Use Of Trapezoidal Lead Screws, Improved Bearings For The Smooth Rods And A Belt Tensioner Adjustment. I Found The Original Design Using The Original Linear Bearings To Be Fragile. I'Ve Also Added A Z Stop To The Motor End. I'Ve Included Holes On The Top Z Shaft Mounts For Kp08 Pillow Block Ball Bearings (Https://Www.Amazon.Com/Gp/Product/B00W8W7Rng/Ref=Oh_Aui_Detailpage_O04_S00?Ie=Utf8&Psc=1) To Further Steady The Trapezoidal Lead Screws. I Don'T Have Them Installed On Mine At This Time However As My Motors Won'T Drive The Additional Load They Impose. Thanks To: Http://Www.Thingiverse.Com/Thing:111903 For The X Adjust Inspiration. Although I Redrew Everything From Scratch, The Design Is Almost Identical To Burtdonalds. Http://Www.Thingiverse.Com/Thing:542892 For The Z End Stop Idea. I'Ve Used The Blackhawk Prusa I3 Rework - Adjustable Z Endstop In My Printer, And Incorporated The Design Into This Upgrade. Take A Look At My X Stop Design At Http://Www.Thingiverse.Com/Thing:1798572. Edit: Updated The Z Shaft Mount Stl Files As It Appears I May Have Had One Wrong. My Apologies. I'Ve Added Different Length Z Stop Arms That Mount To The X Axis Assembly To Accommodate Different Extruders. Pick The One That Works For You. The Short Version Should Always Work, But Will Require A Longer Screw. The Medium Version Is The Original Length. I Don'T Know If The Long Version Will Be Of Any Use To Anyone, But It Is Included. Edit 08-08-18 Added The Sketchup File So That Others Can Improve Upon The Design. I'Ve Effectively Abandoned My I3 Clone For The Time Being As I Am Working With Another Printer When I Have Time.
