I had really great success with these! added some parts to my gantry with them. I wouldn't hang anything heavy, but for adding cable guides and such they're outstanding! Thank you for this!

Pretty soon I'll use them to hang some LED's on the gantry.

Mine are printing out melted together too much to crack apart, guess i'll try lowering the temps and flow a bit...

Great idea. I'll be printing a few out to test. Cheers.

Because G+ is marking me as spam(Check the 'display comments marked as spam' sometime:):
How strong do these end up being? Do you have problems stripping out the threads and I wonder if it's possible/have you thought to cut a nut in half and glue it to create the threads.?

I can't strip the thread by hand, that's for sure... It fits very tight and feels very solid, especially if printed in PLA and screwed entirely. However, don't overscrew since the bottom of the profile will stop the screw and then the thread will lose the battle against aluminum! I guess two of those would hold a spool holder, but it's just what it is...A guess.
No need to mess around with cutting nuts. The burr you will get from the cutting process are likely to render your effort useless.
If you really need strength, follow the suggestions given by Mark Carew earlier in these comments. He knows!

We already use the drop in 'T' nuts, yours just looks like they might not move or slip around as much, especially when tightened up a little bit(The drop in 't' nuts tend to move and fall out if your not carefull when adjusting them). Will have to find a spool of PLA and give them a try!
(And could you please mark my comment on G+ as 'not spam' so google learns? :)

Really Good idea nice Job Thanks for sharing

Cool idea! I have not seen it done this way
You may want to look at couple of 'drop in' tee nut options that can be inserted from the top of the track as well.

Hope this helps

Well, thanks for the compliment and for commenting... The necessity is the mother of invention and I needed to get a Delta 3D Printer ready for the Lisbon Maker Faire which was the day after!!! Since it was just to hold the glass in place, it did the trick. It may help others in need. I wasn't aware of those "originals". Thanks for pointing them out.
