Quick release spool holder nut (8mm)- Anet A8

thingiverse

To swap out a spool on your Anet A8, you'll need to release the quick nut that's threaded onto the 8mm rod. Simply press down on the side of the rectangular part and slide the nut off. Then just insert the new one. First, print three separate parts: one nut and two nut ends. Use PLA filament with a 30% infill setting and skip both the raft and supports.
