Which Version of the Nut traps fit best for 25mm OD 2mm Wall stainless Steel tube? and which version of the nut holder (M8 25mm couplernut) to be used?
That is thick tube, you are going to have to sand them down or cut off the edges. No big deal.
ok. got it. Which version for the nut lock? 11mm or 13mm? where to measure?
The nut locks are for the coupling nut, flat to flat measurement. Shown here, https://www.v1engineering.com/assembly/middle/
Thank you very much for your great design and especially releasing it to the public. Will measure the nut when i have mine on hand… Still on shippment.
