I am having troubles with models like this one:
It prints out nicely but those pillars which are supposed to hold the spools break very easy off by just the faintest touch. I printed the model with PLA 0.2mm layer height and 6 shells, the pillars don't have any infill because they are so thin they consist only of shells (see FFF file for settings, factory file was too big to attach).
I had a similar problem with a filament spool holder I printed for my prusa:
The pillar which should hold the spool just broke off by a slight touch. This one I could fix by printing everything 100% solid with a 2nd process after a certain point, but I don't know how to fix the sewing spool holder.
Any ideas or hints what I could try? My wife was really looking forward to it
