Had trouble printing the little chains on my Ender 3 with glass bed. Tried warmer bed, lower layers, levelled like crazy but nothing worked. I was about to suck it up and try to print a lower amount.. but then I read a simpel trick on the factory store of my filament I was able to print 31 link covers in one go perfectly! The tip? apply a tin layer of a simpel childrens glue stick to the bed. (we call those pritt)
Will post my make later but I wanted to share this in case there others struggling with the print.
