Because the print-bed surface is weak from side to side,
and can be easily tipping down with very light pressure
especially when printing large tall parts,
this upgrade fixes this trouble.

I purchased this kit through Amazon
"JS 1set CR-10S Light Weight MGN12H Linear Rail Y axis Carriage Upgrade for Creality CR-10 300mm 3D Printer".
This kit was less cost then purchasing everything separately.
Kit Package contained:
1 x CR10S 300mm Y Carriage
2 x MGN12H 500mm linear rails with 2 bearing blocks
2 x 2020 V-slot 460mm extrusion profile
8 x 2020 brackets
1 set X M3x8 screws & T nuts

I did need to purchase shorter Aluminum Spacers
".375" Length x .250" Inside OD Dia x .375" Outside Dia": ... UTF8&psc=1
This was so, that the print-bed surface would not be raised up higher.

I also had to purchase shorter M3 screws so to fit
the shorter spacers properly : ... UTF8&psc=1
