ender2 base Z fix

Hi everyone, let's get started. This modification is specifically for those who experience a crooked Z-axis extrusion. I recently discovered that my own was angled at around 7 to 10 degrees, which meant every print I made had a slight curvature. It's unfortunate that I didn't catch this issue until after many prints, as the problem was on the side and not immediately visible when looking at a front-print. Another setback is that both the small extrusion part and the longer piece weren't cut properly, so I've decided to create a base plate that will keep the extrusion straight. As you can see from the photos, there's about an 0.8mm difference on one side. Here are the instructions: 1. Print this modification with a high infill percentage of around 60-80%. It's recommended to use PETG or ABS for this part since it will be near the bed, but PLA can also work well with such a high infill setting. 2. Screws: - For M4 T-nuts: 8 in total - For M4 bolts: 2 x 10mm and 1 x 15mm and 5 x 20mm - Additionally, use M4 washers for added strength Stock parts: You'll need a single M5 standard nut on the back plate. It's your choice where to place it – either under the extrusion or in the middle. If you decide to use two nuts under the extrusion, this modification won't be needed since your part will already have good cuts. Important note: This modification will reduce the overall height by about 1.5-2cm. The first photo shows my initial attempt at this modification, while the second one is a much improved version.
