do you have a version of the nut that has threads all the way through? the threads on the bolt are about 4-5 mm away from being able to screw on to the nut. any help would be greatly appreciated.

I have added an STL that takes the length of the bolt from 100 to 140mm as requested. You can use the same nut.

Thanks for this also. I made the smaller one and was hoping this was longer. Would also like something a little longer. Trying to make a single sided spool holder that I can just put on a roll, spin on the end and be good to go.

See the new file.

You're the best, or at least top 10.

Nice work, thanks for sharing! Is there a chance to get a version with an extended bolt length by about 40 mm? Please see pictures in "I made one". I would try it myself, but because of the thread it's too complicated for doing it myself.
Thanks in advance :-)

After mounting the bearings I found one additional thing which I suggest to change: The inner hole should be at least 12,5 mm, better more in diameter. Otherwise the rotating part of the bearing has too much friction. This could also be done by a drill after the printing, but unfortunately I had to press my bearing into the bolt and cannot remove it again :-(

See the new file.

:-) thanks!

Consider printing the big nut at a minimum.
