My printer is not big enough to print all parts of the Thor project but dannyvandenheuvel has an interesting variation where 2 parts can be glued together. This is the first part I am trying to print. ART2BODYA_1.stl.

See his project here

This part is expected to be an 5h30 job using ABS.

Update: 3 hours into the print the support structures came lose from the bed

I tried to clean the heat-bed and tried again but the support structures again came lose from the bed at 3 hours into the print.

I believe that the moment I start to print a solid layer on top of these support structures, it pulls the support structures up.

This time I continued the print, and the print ended up being usable.
