Spool Holder for M8 Thread Screw

thingiverse

I always face a issue with spool holder can't hold properly and in the end the item will not print properly. i know this design may not be good enough, but one things, it's useful, that's all i need. Once print finish i will update again and also don't forget to print 2 spool cone holder with 608zz bearing and 2 lock, i know it's a lot of plastic when you fail print you wasting more money then that. with infill 20% Layer 0.1mm for smooth beautiful, i believe 0.2mm is fine too, just i love things beautiful.
