As asked for i have uploaded the parts I split, and the one I slightly changed to print better due to the small surface of where the canapy sits (just added two extra blocks which fit fine with the canapy on.

The .stl size and print as normal

The .3mf (cura file) when you open this file in cura you can either import model (which keeps all your setting) or imort as project to change setting how I printed it

Both files set back to 100% size , I printed at 70% and used tree supports on both

Please print the rest of the files from Alpokemon

(pic shows both parts together with the extra tabs marked)
