Bed Levelling Thumbwheel for Wanhao Duplicator i3
thingiverse
Update 27/11/16: Thinner Bottom Allows for More Screw Engagement I Tweaked the Design to Make Holes Smaller, Ensuring a Tighter Fit. This Remix of Webberen's Bed Level FingerKnob (http://www.thingiverse.com/thing:1032666) Was a Necessity. The Original Round Hole Was Too Small and Hex Hole Too Large, Causing the Nut to Slip Out. I Suspect This Was Due to My Printer's Inaccuracies in Dimensional Measurements. This Version Features a Larger Diameter and Greater Thickness, Similar to Stock Metal Thumbwheels That Come with V2.1. It Uses an M3 Nyloc Nut, So I Deeperened the Hole for Better Seating Inside the Thumbwheel. I Printed Them with 1.2mm Top/Bottom Shells and 2mm Walls, But You Can Get Away with 1.2mm Walls Too.
