Y carriage made of 2020 aluminium extrusion profile

I am currently constructing an AM8 printer. However, I initially thought that the original Y carriage was excessively flimsy and might be bent by the leveling screws. I had some leftover 2020 extrusions from my other projects and believed I could manufacture a carriage from them. So, I designed it in Fusion360, and here is the result; To build this printer, you will need the following metal components: - Two 2020 Extrusion profiles measuring 220mm each - Two 2020 Extrusion profiles measuring 149mm each - Four Aluminum Angle Corner Joints with dimensions of 20x20mm (https://www.banggood.com/10pcs-20x20mm-Aluminium-Corner-Joint-Right-Angle-Bracket-Furniture-Fittings-p-1056722.html) - Twenty-eight or thirty-six M5 square nuts - Twenty-eight or thirty-six M5 x 10mm screws - Two M3 hex nuts - Two M3 x 12mm screws In addition to these components, you will need: - Four LM8UU linear bearings - A heated bed with a screw hole distance of 209mm. (Anet A6/A8 heated beds measure 209mm x 209mm) This design works seamlessly in conjunction with "My Y axis belt tensioner for AM8" (https://www.thingiverse.com/thing:3240583).
