Filament Thrust Bearing
Description
Is It Really Necessary To Mount Filament Spools Vertically? Vertically Obviously Has The Least Chance For Gravity To Mess Around And Entangle Layers On The Spool. But Let'S See... This Is A Thrust Bearing For Mounting A Spool Horizontally. It Centers Spools With A 19Mm, 32Mm Or 52Mm Hole Perfectly. Or Any Other If You Don'T Mind That It Moves A Bit Sideways.. To Better Fix Spools On The Center Pin, Some Caps Are Available. Basically A Cone Centers The Upper Side Of The Spool. There Is A Short Cap, For Extreme Narrow Spools And A Long Cap For Very Wide Spools. But In General The Sponge Cap Should Be Able To Cover Most Spool Types. The Design Was Done With Freecad Exercising The The Sketch Feature For Most Parts. The Bearing Uses Conical Rollers And Features A Bottom Opening, Where A Pin Can Be Inserted, So That It Will Not Fall Apart As With Other Thrust Bearings.
