Prusa Mendle X ends - low profile
Description
As My Desk Space Is Limited I Wanted My Prusa Air 2 To Take Up As Little Space As Possible. It Bugged Me That The X Carriage Stepper Sticks Out So I Designed These To Allow The Motor To Sit "Behind" The Z Rod & Z Axis Screw. The Compromise Being That The Nema 17 Stepper Retaining Screws Are Difficult To Access So I Have Included 2 Holes For The Bottom 2 Screws Where The Allen Key For M3 Screws Passes Through. Can Only Be Used When The Bottom Lm8Uu Isn'T Fitted As Well As The Top Z Nut And Backlash Spring. While I Was At It I Have Implemented An Idea For An Adjustable Idler Pulley So The X Drive Belt Can Be Leveled With The Carriage X Rods Whether You Use A Standard 608 Or 607 Bearing, With Or Without Idler Pulley Like A Gt 2 Idler Pulley > Http://Www.Thingiverse.Com/Thing:45955 I'Ve Seen This Kind Of System Before But Cant Remember Where! I Haven'T Printed Or Tested These Yet But Will Do So In The Coming Days. Updates Sept 17> Just Updated Idler Xend To Idlerxend 2A With Some Minor Chamfer Additions To Aid Printing. Added A T2 -40 Tooth Idler Pulley To Fit Standard 608 Bearing Sept 18 > Found A Chamfer Fault In Motor X End ..Now Updated To Rev 2A Problem With 40T Idler Pulley ..Wall Thickness Between Idler Teeth And Bearing Was Very Thin....Added 41 Tooth Version Sept 20 > Issue With Nema 17 Bolt Hole Spacing In Motor X End Resolved. Stl File Updated To Rev 2B Motor X End Sept 24 > Added Rev 3 Motor & Idler X Ends. Lowered The Overall Height Of Both The Lm8Uu Containment Tube And M8 Backlash Nut Holder & Added A Chamfered Gusset Between The Two. All Comments Welcome
