Sorry for the reddit link, but this is a really cheap hack, to get a better frame.

Print some parts, add nuts and bolts and use a proper method to adjust the frame.

Other modifications:

• direct drive
• enclosure
• replace the main board or at least adjust the vRefs, check the main board version.
• use Klipper to let it calculate the compensation for linear advance
• print something like a brissfang (also compatible with a microswiss direct drive) to get better part-cooling.
• camera
• replace the bed springs with silicone
