This is a LME8UU case tested in metallic linear bearings. Tevo tarantula Y axis upgrade: This alows you to use the stock acrilic base to upgrade to dual Y rods. You also will need 2 450x8mm rods and front and back rod holders. You can use whatever but just be sure that has the correct height. The acrilic base MUST be highter than the 4020 aluminium center profile. This design level up the acrilc base 8 mm from the center of the rods. So i recommend you to use front and back holders with a 34 mm or more height to have at least 2mm clearence between the acrilic base and 4020 profile. I am using a 42 mm height of my own.

First of all, download or design the front and back mount you are going to use. Mesure distances between rods. Then do a drilling template (2D printer). Start using a small drill like 1,5mm or 2mm. In order to be very accurate in the assembly you should drill LME8UU case 4mm holes in the M3 holes, this will alow you to correct the error. Assemble all the 4 LME8UU case to the acrilic base but just tight a little. With the base upside down insert the rods and mesure the distances with a caliper. Correct the distance error and tighten it. Check if the rods can run smooth before assemble in the printer.
