2020 Corner Bracket, no screws needed

thingiverse

Place the larger half of the corner bracket onto the V-slot profile, ensuring a snug fit. No disassembly of the frame, T-nuts, or screws is required to assemble this critical component. Next, slide the smaller halves into place via the profile, carefully aligning them with the larger piece. The locking bar will then be positioned over these smaller pieces, securing it firmly in place against the larger half. For optimal strength, print the bracket vertically, as this orientation will maximize its structural integrity. If the assembled bracket feels loose or wobbly, simply adjust the first layer of the print to a slightly higher setting, and reassemble the component for a secure fit.
