Neva Brick Spool Mount

Description

Neva Comes Without A Spool Holder And You Are Expected To Print One Yourself. I Used The [Dagoma-Designed Spool Holder](Https://Www.Thingiverse.Com/Thing:2365668) To Hold A Spool At The Top Of My Neva. Dagoma'S Design Works Really Well But There Were A Few Annoying Things That I Decided To Solve By Making My Own Spool Holder From Scratch. Here Are The Goals That I Pursued: - **Neva-Tailored Shape** (Spool Holder Should Maximally Make Use Of Neva'S Dimensions); - **Secure Installation** (The Holder Should Not Partially Grip The Bar Or Bend, Or Wobble); - **Slim Profile** (The Spool Holder Should Be Minimal In Size, So You Can Mount It Close To The Wagon Rails And Reduce The Angle That The Filament Creates While Entering The Extruder); - **Minimal Friction With The Spool** (The Spool-Holding Arm Should Be Maximally Round, So The Spool Will Easily Glide On Top Of It); - **Support Of Multiple Spools Sizes** (Up To 10Cm In Width And 1Kg In Weight). --- ###How (What) To Print, Install, And Use First Of All, You Have To Print The Brick Which Consists Of The Main Body, Door, And A Screw (Available Both As Separate Parts And As A Combined Model). Then Depending On Your Desired Spool Width, You Have To Print A Spool Arm (Available In 6Cm, 8Cm, And 10Cm). You Can Also Adapt To Another Spool In The Future By Just Printing A New Arm And Replacing It (How Cool Is That). Also, Because You Print The Arm Vertically The Surface That Touches A Spool Is Very Round And Smooth. The Assembly Instructions Are Also Available Among The Photos Of This Thing. In Short, They Are: 1. Put The Brick Body Around The Top Bar Where You Plan To Mount The Spool. One Hole Should Face Up (This Way The Screw Will Not Interfere With Magnetic Arms) The Other Hole Should Face Outwards (I Suppose You Don'T Want To Mount Your Spool Inside Of The Printer). 2. Slide The Door Bracket Onto The Brick So That They Form A "Solid Cube". 3. Screw-In The Screw On At The Top Of The Bracket And Make Sure That The Bracket Is Securely Attached. 4. Screw-In The Spool Arm To The Side Of The Brick With A Counterclockwise Movement. The Spool Will Unwind Counterclockwise And This Movement Will Contribute To The Tightening Of The Arm Attachment. The Arm Doubles As A Securing Screw As It Goes Into The Cavity Of The Brick And Presses Against The Neva Top Bar. --- #### Safety Warnings This Is A Tricky Design That Relies On The Interoperation Between Quite Thin Parts Of Different Components. For Example The Attachment Of The Door And Especially The Attachment Of The Arm With A Screw Thread. I Printed This On Neva Using The Dagoma-Provided Cura With 33% Of Infill. I Used It For 1 Week With A 1Kg Spool, And It Worked Perfectly. However, If For Example Your Printer Underextrudes You May End Up With A Thread That Is Not Strong Enough And Can Break At Some Point Causing Damage Or Injuries. This Is Why A Beg You To Use This Design At Your Own Risk, As **I'M Not Taking Any Responsibility For Potential Damage**. Having Said That, I'M Open To Any Feedback And I'M Interested In Improving This Design As I Use It For Myself And I Want It To Be Helpful For Others.
