Just printed the Base_on_2020_Al and it came out great, until I took it off the bed and the tip where the spool attaches snapped off on both prongs to down to the narrowest part of the taper. I was using 0.25 mm layer height out of a 0.4 mm nozzle and that portion of the print was solid PLA with no infill, any advice on how to avoid this on my next attempt would be appreciated.
