I’ve searched the forums with no luck. In some of the other models constituting my patented device, I need to incorporate NPT (1/4") threaded ports. Are there ‘blocks’ available somewhere?
I would also like to find models of the following parts.
Pressure gauges (back & bottom ports)
Cornelius keg adapter
Gas and Liquid Ball-Lock fittings
Gas and Liquid Ball-Lock adapters
Pressure Relief Valves
This is not for actual construction models. I would like to be able to obtain complete renderings.

Have a look at http://www.food4rhino.com/project/boltgen?etx as a starting point for the threads… The rest of it is very easy and quick modelling.
If/when you create them you could make them free on GrabCad or maybe sell them on TurboSquid…
Nice AddIn and it does a nice job, but no NPT.
McMaster has a ton of stuff available in various 2d and 3d formats - haven’t looked for precisely the articles you want though…
I think I found that very beer keg tapper on GrabCad, have a look there.

Thanks to all. I think I found some useful parts. Now to unzip them and see what I have.
Not the same. I will try and modify it to work…
