2040 Aluminum Extrusion DRILL Helpers
Description
I Made These To Help Drill Holes In 2040 Extrusions. These Are Universal With The Exception Of One Piece Which Is Made For The Prusa I3 Bear Mod. All You Need To Do Is Bolt These To The Corner Of Your 2040 Extrusion Use Two (Or More) T Nuts To Bolt Down The Plate And Use A 13/64 Drill Bit To Drill Through Each Hole. They Are Designed To Be A Little Smaller So The Drill Bit Cant Self Center. The Long (Bear Mod) Drill Plate Has Two Holes At 96Mm From The Edge. All The Other Holes Are Random To Help Stabilize The Plate As You Are Drilling. To Open The Hole Up You Will Need A Step Drill (Christmas Tree Bit) Bit Or Larger Drill Bit. One Set Is Called Std Other Is Called Misumi. For Misumi Extrusions I Found The Holes Are Slightly Closer Vs The Std Version. After Drilling You Will Need To Use A 4.2Mm Drill And M5X.8 Tap To Tap The Holes They Need To Go In. Most Extrusions Are Already Predrilled For 4.2 So You Only Need To Use A M5.X8 Tap. M5 X.8 X25Mm Screws Are Long Enough For 2020S If You Want To Go Through At 40Mm You Will Need A M5X45Mm. Only Left Sides Were Uploaded. To Use On Right Side Use Your "Mirror" Function In Your Slicer
