Thanks for the information on your dampers. The Amazon listed dampers I bought stated that they were 6 mm thick. Either I've been sent the wrong ones or the listing is wrong.
I've also wasted a load of time and filament printing your X-axis mounting plate as well because it will be for 6 mm dampers too :((
Is it possible to add an updated spacer to fit my 8.68 mm dampers please? The same for the X-axis solution as well please.
