Filament spool roller Spacer - Connector

Hi,
I have designed a spacer for the filament holder. Since I had the problem that the two brackets have always shifted against each other on smooth surfaces and thus the filament roll was no longer optimally guided.

If you have problems or suggestions, I will gladly help.

Thank you jstck for the "Filament spool roller" which I used as the basis for my spacer designed.
