Y Carriage Bearing Mounts for Folger Tech 2020 i3
Description
Tl;Dr - Bearing Mounts For The Folgertech 2020 I3 That Can Hold 1X Lm8Uu, 1X Lm8Luu, Or 2X Lm8Uu. No Zip-Ties. I Was Wanting To Learn Fusion 360 And Upgrade My Printer (Folgertech 2020 I3) So I Started With The Bearing Mounts On The Y Carriage. It Used The Common Configuration Of One Bearing On One Rail And Two On The Other. This Is A Forgiving Arrangement, But Can Introduce A Bit Of Slop From The Play In The Single Bearing. If You Have Good Rods And Make Sure They'Re Aligned Properly Then Extending The Single Bearing Can Make The Bed A Little More Solid. I Also Never Really Liked The Idea Of Using Zip-Ties To Assemble A Precision Machine, So I Designed These To Hold The Bearings Without The Need For Zip-Ties. Dimensional Info: 28Mm Between Bolt Hole Centers 18.5Mm From Bottom Of Carriage Plate To Bearing Center Designed For 12Mm M3 Bolts And Nuts (Assuming 2.5Mm Plate Thickness) Includes Hexagonal Recesses To Hold The Nuts. I Tested The Temperature On The Underside Of My Carriage Plate And Found That At Bed Temps Required For Abs The Underside Temperature Would Approach The Limits Of Pla, But Were Well Within The Limits Of Petg, Which Is What I Used For My Final Versions. Note That I Have Insulation Between My Heated Bed And Carriage Plate Though, So You May Want To Test For Your Setup Or Just Play It Safe And Use Abs.
