EleksMaker EleksLaser A3 Pro Laser Engraver Upgrades

I recently upgraded my older EleksLaser A3 Pro laser engraver and wanted to share those enhancements with others. Although I haven't verified these modifications will work on the latest version of the A3 Pro, based on pictures they should. I've included .stl, .step & Fusion 360 file formats for my designs. See "Upgrade Instruction.pdf" for more information about both the components you need to print and hardware you need to purchase. Notes: 1. Most of the new hardware I needed were contents of a larger hardware kit I had previously purchased on Amazon (https://www.amazon.com/dp/B07MN9X2KN/ref=cm_sw_r_tw_dp_U_x_iU6bDbHXCZG5E). I believe these kits are an excellent buy and significantly cheaper in the long run than buying individual fasteners for a specific project. The only hardware I sourced from my local hardware store was the M5x50 Bolts, M5x6 Button Head and M4 Nylon Lock Nut. 2. You may not have enough nylon spacers from the original A3 Pro kit to do the y-carriage upgrades. I had just enough extras leftover from my original build even after replacing a few cracked spacers. If you need more spaces, I would recommend checking out these projects https://www.thingiverse.com/thing:3035351 OR https://www.thingiverse.com/thing:2501088. 3. You will need to verify the focus of your engraver after this upgrade since it moves the engraver away from the work surface. I wasn't sure if this was worth mentioning but for completeness, I figured it was worth mentioning. Final Thoughts: At the end of the day the out-of-the-box laser engraver worked well and I used it for several months without any modifications successfully. The improvement you see from these upgrades will really depend on what you started with. I had an x-carriage that was too tight out of the box and a y-axis that was too loose. I noticed the biggest improvement when engraving the same thing over and over again, and there wasn't any "shift" in the design on the work piece. If there are any other upgrades/improvements you think I should try let me know in the comments.
