I put an E3D Toolchanger that I got for cheap from Aliexpress on mine, with 2x E3D v6 and Trianglelab TBG-Litle direct drive extruders. The TBG-Lite is amazing. It's got so much grip on the filament, that I didn't even end up setting up a TPU profile at all, I just used a PLA profile for it.
I ended up switching over to a Snapmaker U1 earlier this year, and the only thing I miss are these TBG-Lites.
