Prusa I3 Z Axis Adjuster
Description
You Will Need A Couple Of 3 X 20 Mm Adjustment Screws To Complete. I Drilled A Mounting Hole In My Existing Z Endstop To Allow It To Be Mounted On The Stepper Motor Plate. I Had To File A Square Area For The Limit Switch Since It Had To Go On The Other Side. I Suggest Using Pla As It Is Harder And More Stable Than Abs. For The Arrow Component, Make Sure You Start The Threads So The Screw Goes In Straight. I Did This While Still On The Bed. Then When You Thread It Onto The Adjustment Screw, Allow The Screw To Protrude About A Quarter Inch Past The Disc So That Only The Screw Engages The Limit Switch. If You Insert An M600 Command At Layer Height Z=2.2, You Can Change Filament Colors To Have A Contrasting Color For The Arrow. Edit 12/19/2017: Added Version 3 Which Uses A 3Mm Nut Pressed In With A Pair Of Pliers For A Tight Fit And Two 20Mm Length 3Mm Fine Thread Screws For Securing The Bracket And One For The Adjuster Screw. My Original Version Was Starting To Show Some Wear In The Threads Because I Did Not Use A 3Mm Nut, So I Reworked The Stl File To Include It.
