I made the reinforment to get a better angular alignment (perpendicularity of X and Y-Axis).
That is also the reason why I printed it on my MK3S because the MK3s has perfectly aligned axes.
The reinformcement is designed for M5 screws and T-slot-nuts.
I printed it with the standard settings for 0,2mm Quality.
