Spool holder (for common 0,75kg spools)

Description

Hi There! To Print This Spool Holder I'D Advise You To Print In Abs, Xt Or Other Materials, That Can Be Drilled. I'Ve Used Colorfabb Clear Xt. The Spools Are Specially Made For My Colorfabb Spools (200Mm Od, 55Mm Thickness), But Most Spools Will Work. What You Need: Spool_Holder_Base Printed Twice Spool_Holder_Arm Printed Once 8 M5X20 Or Similar Length, No Less Then 15, No More Then 30! Preferably Countersunk, But All Heads Work. ~25Cm Of Rod, Od 6Mm, Id 4Mm, Preferably Metal (Aluminium) E3D Bowden Coupling Http://E3D-Online.Com/Mechanical/Bowden/Bowden-Adaptor-1.75Mm-Filament 4 Ball Bearings 625Zz 5Mm Drill (If Possible Also 5,5Mm) 6Mm Drill (If Possible Also 6,5Mm) 12Mm Drill (Up To 13Mm Is Fine Too, But At Least 12Mm) Drill For Countersinking (If You Use Countersunk Screws) M5 Tab, If Possible Also Some Cutting Fluid Assembly Of The Base: Take Both Printed Bases And Drill In The Holes With A 5Mm Drill, To Get A Good Bore, You Can Also Use 5,5Mm Drills, Which Will Make The Assembly A Little Bit Easier, But Don'T Drill Too Wide Holes. If You Use Countersunk Screws You Should Also Sink The Holes Accordingly. Make Sure To Sink The Flat Side Of The Bases, There Is A Little Ring Sticking Out Of One Side Of The Bore, Do Not Remove It ! Take The Rod And Cut Them To The Following Lengths: 2X 47Mm 2X 59Mm Drill M5 Threads In All Sides Of The Aluminium Rods. Take The Spool_Holder_Arm And Drill 6Mm Holes In The Two Exsisting Holes, Due To 3D Printing The Holes Might Be Too Narrow. To Ensure Easy Fitting You Can Also Use A 6,5Mm Drill. After That You Have To Drill The Open Bore At The End Of The Arm With A 12Mm Drill, I'Ve First Used A 12Mm One, Then 13Mm To Loosen The Snapfit A Little Bit. Take 4 Screws And Push Them Through The Holes Of One Base, The Heads Are On The Flat Side Of The Base. Take The 59Mm Long Rods And Screw Them Onto The Lower Screws. Take The Ball Bearings And Put Them On The Thread Of The Upper Screws, Now Screw On The 47Mm Long Rods Against The Bearings. Before Proceeding Similar With The Second Base, You First Have To Push On The Spool_Holder_Arm On One Side Of The Rods. After That You Can Screw On The Second Base To The Rods And Tighten Everything. Your Spools Should Now Drop Easily Onto The Spools And Should Spin Freely, The Filament Can Be Inserted In A Bowden Tube, Which Is Held In Place With A Snap-Fitting Bowden Addapter. If The Spool As Too Much Play Along It'S Spinning Axis (Too Wide Spool Holder), You Have To Remove One Base And Take A File To Shorten The Rods, This Is Only Necessary, If The Clearance Between The Spool And The Bases Is So Large, That The Spool Might Fall Off Of The Bearings. To Hold The Arm In Place You Can Use The Small Holes To Drill Through The Arm And The Aluminium Rod, After That You Can Taper The Alumnium Rod And Screw In A M3 Screw. My Arm Fits Neatly On The Aluminium Rods And There Was No Need To Use Those Screws For Me. To Use This Spool Holder For Smaller Or Larger Spools, You Have To Adjust The Rods Length, Make Sure To Have The Smaller Ones Allways 12Mm Shorter, Then The Longer Ones, To Compensate For The Bearings And The Spacer On The Bases.
