Anet A8 50mm spool adapter (low friction, no bearings)

This spool adapter fits all spools with a hole 49.7mm or bigger, fits loosely over the stock threaded rod and requires no additional parts.

**Assembly:**
Please take a look at the photo, it's quite straightforward. Note: the nut and the counter-nut should be tightly screwed into each other, or they will come undone.

**Why this adapter is good:**
- Designed so you don't have to unscrew anything to change filament
- Doesn't waste filament, but it's strong enough
- Quick to print
-
