I don't like the hard fixings for the filament spools, I wanted to be able to move them and remove them as I wanted on my wooden board.
There is no problem with 1kg, it does not move at all, but with less weight the bobin could move.
Adapted for my desk, be aware measures inside, there is 2 holes on my board, but you can esaily do if missing.
Done with Windows 3D Builder and Meshmixer.
