a other nut for filament spool holder

The original are great. I printed the Original version. But this fits not with my filament spools, so I created quick and dirty this remixt nut. You can print the original version with more Persent high for bigger spools, but I dont like to print twice. So just this modification.

Now I found a bigger version of the original:
