Binding post Round Plate
thingiverse
I am in to making speaker this days and the other day just spend 5 pounds on a back plate like this one to realise as soon as it arrived that I am a maker... So I got the calipers, toke a couple of basic dimensions and made my own. Now you only need to buy the plugs which are way cheaper. Also missing in the tech drawing the holes for the post are 4mm diameter. For example: https://www.ebay.co.uk/itm/Binding-Post-Terminal-Speaker-Test-Plug-Socket-Connector-Gold-x-4-Pairs/292157390905?hash=item4405f00039:g:PBoAAOSwty5a-Pt5
