Tool Post for Mill Turning

I was in the process of converting my mini lathe into a CNC machine when I stumbled upon a video from Lucas Is Busy that completely changed everything. He had posted a modified post processor for Fusion360, and I couldn't be more grateful. However, I quickly realized that there wasn't a single tool post CAD design available for milling machines, so I decided to lend a helping hand to the community. I designed a tool post that fits a 4-inch vise and currently has four mounting points for 12x12 lathe tools (including right-hand turning, parting, and finishing tools). It also features three holes for boring and spot drilling, as well as a mini drill chuck with a 1.5-10mm M12 x 1.25 thread mount to secure it to the tool holder. You can find similar products on AliExpress (https://www.aliexpress.com/item/32678799353.html?spm=a2g0o.cart.0.0.24623c00xwa6XH&mp=1) or Banggood (https://www.banggood.com/SAN-OU-1_5-10mm-Metal-Stable-Keyed-Drill-Chuck-Convertor-M12x1_25-Thread-Chuck-Adapter-p-1288813.html?rmmds=detail-left-hotproducts__5&cur_warehouse=CN). The principle is simple: you home your G54 at the top right corner in X, Y, and Z, then offset for each tool in G55, G56, G57, and so on (you can watch Lucas' video to get a better understanding). Once you've got your stock part in the spindle, you'll only need to reference Z in G54 at the top of the tool post, and the post processor will take care of everything else. I've attached both step files and the Fusion360 project for you. I hope this can be a good starting point for your final design. Edit: I've added Version 2, which is what I'm probably going to make next. The step files include an assembly.
