Anyone with a 3d printer want to test print my project?
Alex Rich wrote 05/12/2015 at 23:59 • 1 pointI'm working on a ball and socket "gooseneck" project that is 3d printable. The novel feature is a locking nut on each joint that vastly improves the pullout strength of the joint.

Works great when printed with the Stratasys I have access to at work, but obviously I am spoiled with soluble support material, heated build chamber, etc. Is anyone with a consumer grade printer interested in test printing a few links of my ball and socket joints and reporting back on how well it works? STL files can be downloaded from my project page.

I need some one to see how well this works, no 3D printer my end to try it
Model Diesel Engine Starter 3D Printer files
The files do need some work!!!
Advantages include:
Lightweight portable and no battery required.
Method uses a wound up spring, held against a ratchet), it's stored energy

Seems to work well enough. Send me your address and I'll mail it to you.

Awesome! @Peter Walsh Thanks for testing it for me. Each link is comprised of the parts "main body," the ball and socket; as well as "twist lock," the nut. There is also an end attachment part for holding an alligator clip, you don't have to print that if you don't want.
I'm in Virginia, not to far, but don't feel like you have to ship it. I'm just curious to test the process of other people printing the pieces and getting them working on their own. It may work right out of the printer or may require some work to get things to fit (or it may be a total fail).

Hokay - had a lot of people queued up at the printer tonight, and I stayed at the end of the line to let real projects go first. Then I had a problem with the slicer that took some time to resolve with the resource manager (person in charge of the printer), then it was too late to start the print.
Next week I'll try again.

My space has open house on Thursday nights (tomorrow), and like to have things printing while giving tours to potential members.
It's on my thumb drive, I'll let you know how it goes.
(What country are you in? I might send you the results.)

@Peter Walsh,
I have a tip for getting this dialed in for your printer. Print several of the twist-lock nuts each scaled 100% 102% 104%. Then test to see which one fits the best before printing a large chain. You should be able to twist them on with a firm twist without resorting to a wrench (depending on how sweaty your fingers are). It appears each printer is a little different so you will need to compensate a bit to get things just right.
The STL files I posted work well for my printer, but @Mike Rigsby printed some today on his MakerBot Replicator 2 using PLA at medium resolution without supports and found they were a bit tight. He needed to use a wrench to fasten the nut, so scaling to 102% or so will probably dial it in perfectly. Let me know how it goes on your printer, thanks again for the test!
