[QUOTE=CarinaPDX;1460356 The ends of the gooseneck have 1/8" IPS (straight pipe thread) so I need an attachment to the fan body that is either threaded or has a hole for the male thread and room for the nuts. Any ideas? ABS would be a good material.
Sure. CAD up a frame that encloses the fan, has tabs for the four mounting holes, and a fitting for your pipe thread. Easiest would be to just design in space for some flat nuts. They could be recessed into the "holder".
I bought one of the early PrintrBot printers from a Kickstarter program. Crowd financing
. Putting the thing together was a challenge. A box of parts
and no manual. But after a while it started making sense. And that was the easy part. If your nephew is a double E then he's already familiar with CAD programs. What's the holdup?
My first project
was just a replacement knob for my wife's Crock Pot. Since then I've done lots of projects with it. Dozens on the boat alone. Printing up a little catch to hold my engine
room hatches open while I'm below. Getting rid of the bungy and metal hook routine. I get a fair bit of email
about this stuff when I post photos on the blog. Lot of interest out there. I definitely want one on the boat, too.
OSU? I did some work for those guys way back. Tracked a submersible around the bottom of Crater Lake looking for hydrothermal vents. Deep Rover. Fun trip.
