FlSun Delta Upgrade

I basically bought the FlSun Delta for the parts (extrusions, rods, heated bed, display, board) as this was cheaper than buying these components separately on AliExpress and I assumed I would have to upgrade some parts.

I first built the printer as delivered and found out I couldn't easily get it orthogonal and stable as expected.

I slightly modified Rocholl's original Kossel design for FlSun's 2020 extrusions and to use M4 hammerhead nuts, instead of the M4 square nuts.

This 20 USD/EUR/GBP upgrade (filament and hammerhead nuts) makes a big difference in putting together a square delta frame. Downside is, of course, that you need access to a working printer.

Tolerance for the 2020 profiles is 0.2mm. If this is insufficient for you, let me know and I can provide a version with a tolerance that matches your printer's capa
