Anet Spool Holder Conversion and spool adapters

This is a simple conversion for the Anet Spool Holder. I wanted it to put a 150mm axle (diameter 8mm) on it instead of the threaded bar. So all you need is two M4 screws and nuts and a 150mm axle, which you can get for a few bucks from aliexpress.
I also made adapters for a few different filament spools, whenever I make new ones, they will be uploaded. You can use 3mm screws to secure the spool on the adapter even though the adapters sit pretty tight. In most cases you won't need them.
Need an adapter for a specific spool? I need the hole diameter and the diameter for the drill holes. As soon as I get to it, I'll make them.

Any ideas, questions, suggestions? Just comment. You made one? I'd love to see some pictures! :)
