creality CR10 ender 2 3 Xbelt align mod/fix

I passed a few forms posting some good mods for our printer, so now I've decided to post these fixes that I noticed were really needed on our printers. This is intended to make the X belt straight with the 2020 aluminum extrusion. In many cases, it tends to rub on the lower part/left of the printer, adding an idler near the 20T motor pulley. Technically, it will also improve accuracy on the X axis, but I think that can be really seen except for the axis, which is 60-80 cm long. Parts needed: 2 # M3 x10 mm bolts for Part 1 1 # M3 nut for Part 1 1 # M3 locking nut for Part 1 (You can use a standard nut, but a locking one would work better) 4 # M3x30 mm bolts for Part 2 2 # M3 x10 bolts for the endstop. The original ones are okay, but be careful while screwing them; they're bad quality. (Idler part) You'll need one of these: either 1 # 16-tooth idler with a bearing bore 3 mm bore bearing without teeth or 1 # 16-tooth idler with a bearing bore 3 mm bore bearing with teeth or 2 # F623ZZ bearings with 2 M3 washers (the last choice, but it should work without problems) NOTICE: To understand the parts better, I've made some photos of them. Mounting (check the photos): Step 1: Insert the two nuts into Part 1. Step 2: Screw Part One onto the structure-motor. Step 3: Screw the endstop with the two bolts (if using the original bolts, go slowly) onto Part 2. Step 4: Insert the 30 mm nuts and the idler onto Part 2. Step 5: Put everything together and then insert the belt. Tension everything, and you're good to go with a parallel straight belt.
