I'm setting up to do production runs of these and an all-metal version. If I can remember, I'll message you when I'm ready to ship. Otherwise I will post more videos with info (link to buy etc) in the coming months

Basically the screw is just providing clamping force so if you can find any 40-50mm long screw under Ø5mm dia you're set. Are you saying you've got access to a 3d printer and filament but no source of screws?

@@Octopusbeak I meant the thumb nut on the top, I have a similar design and I was looking for thumb nuts like yours

@@frcobra666 Gotcha-i got it from US hardware supplier. ebay, banggood, aliexpress have them. "m5 thumb nut". I bet there would be something vaguely similar tapped m5 at a bicycle shop. could also 3d print knob with a brass or steel insert

@@Octopusbeak hey there, I wanna ask you if you could explain me how to do such extrusions for the 4 different measures? I'm designing a similar compass and I'd like to add these you have if you don't have any troubles with it
