MakerFarm i3v Heat Bed Wiring Strain Relief

Description

This Mounts To The Rear Of The Y-Bed On A Makerfarm Printer And Provides A Strain Relief Point For The Heat Bed And Thermistor Wiring. The Design Originally Focused On Providing A Support With A Curved Arc That Matched The Round Tab Extension On The Wood Type Makerfarm Y-Beds. While The Makerfarm Tab Is Intended As A Wiring Strain Relief Point, Moving The Cable Tie Location Farther From The Edge Of The Y-Bed Provides A Better Strain Relief Approach, Especially When Large Gauge Wiring Is Used For The Heat Bed. In Addition To The Arc-Type Support, The Final Openscad Script Can Provide A Support With A Simple Block That Presses Against The Straight Edge Of An Aluminum Y-Bed. Use Of The Block-Type Support Requires Mounting Holes To Be Drilled Into The Aluminum Y-Bed. Selection Between The Two Types Is A Parameter In The Openscad Top Level Geometry. Changing Between The Two Types Typically Also Involves Changing The Parameter For The Y-Bed Thickness To Match The Wood Vs. Aluminum Bed Thickness. The Two Stl Files Provided Are For An Arc-Type Support For Use With A 6-Mm Thick Wood Y-Bed And A Block-Type Support For Use With A 3-Mm Aluminum Bed. The Cover Photo Shows The Arc-Type Support Installed On An 8-Inch Makerfarm I3V Printer With A Wood Y-Bed, Using 1/2-Inch #4 Pan Head Screws. M3 X 12Mm Screws Would Also Work. Compatibility With Other Size I3V Printers Or Printers With An Aluminum Y-Bed Has Not Been Tested. The Openscad File Has Been Extensively Commented For Those Wishing To Tailor The Strain Relief Bracket. Note: For A Version That Raises The Strain Relief Surface Higher Off The Print Bed And Offers Recessing Mounting Screw Heads Into The Bracket, See The Remix At Http://Www.Thingiverse.Com/Thing:2010943.
