Filament Holder

cults3d

I've been struggling with a pesky problem on my Wanhao Duplicator 5s Mini printer - PLA filament keeps breaking just before the Filament feeder, and I suspect it's due to excessive bending from the spool to the feeder. After some digging, I'm convinced that the culprit is the current spool holder placement, which causes too much strain on the filament. To fix this, I've built a custom spool holder that screws into my printer cabinet below the feeder, effectively reducing the bend and hopefully preventing future breakages. To help others tackle this issue, I've included the 123d Design file - feel free to modify it as you see fit! For reference, I printed mine at .20 resolution with 20% infill.
