Fuel Vapor Separator - Design Opinions Wanted (1 Viewer)

[Andrew S]

Very cool, I should buy one for the inevitable failure of my own vapor separator.

Easy option for tapping straight is to print a quick guide block with a clearance hole for the tap. Since you've already modeled your part-to-be-tapped, you can make the guide block fit snugly to the part body wherever you need it to be.

Another option is to model the threads and let them be printed. Then just run the tap through to clear out any flashing.

Update:

3D printer is set up. Have a dedicated space now, plus a filament drier (the large dehydrator), a dry box for a 5KG roll of Nylon, and we're off to the races. Kids are enthralled:

Working on dialing in print settings for nylon... Aborted the first print after 15 or so layers as the edges were curling. Here's what that was looking like:

Knocked down the fan speed to keep temps up and the current print is looking much better thus far, but I can tell I'll need to be dialing in surface finish. Here's the current prototype:

They said Nylon is a PITA, and it seems to be living up to the reputation, but I think it will be manageable.

I have read that you need to dry the nylon filament to get better results.

That's right, I dried it for around 6 hours at 70C / 160F, but after this print I may do a full 24h and see how that goes.
