Parametric horizontal spool holder (DIY bearing)

Description

Horizontal Spool Holder For Anet A8. If Mounting On The Top Like I Did You May Need To Shave Off A Small Section Of The Frame So The Spool Doesn'T Rub. I Haven'T Tried Printing With It Yet But It Does Spin Nice And Smooth. I Expect I Will Need To Make A Filament Guide To Ensure The Filament Does Not Slip Off The Side Of The Spool. Edit: It Works Excellently And I Made A Simple [Filament Guide](Https://Www.Thingiverse.Com/Thing:2514784) Compliment This Spool Holder. The Stl Files Are Optimised For Rigid Ink Filament With A 54Mm Inner Diameter, But The Scad File Is Attached For Anyone To Make Their Own Version. I Wanted To Make A Holder Which Would Fit In The Reasonably Confined Space Where I Keep My Machine And I Didn'T Want To Wait For Bearing So I Used Some Steel Balls I Had Laying Around. These Are 12.5Mm Balls Like Those Found In Sets Of Geomag. You Will Need 16 Balls In Total. 13 For The Base And 3 For The Top.
