sturdier PLA spool

thingiverse

I struggled with printing this in PLA and the spool snapping at the string holding point, so I revised it to have a smaller opening and rotated it 90 degrees - now I'm about to put it to the test shortly. Update: after printing it, I discovered that the hole comes out fine, but was too small for my string; it might work with various threads or smaller strings, though it's still significantly more durable, and simply taping or supergluing the string on has worked beautifully.
