This is a sharing from the original creator's (Samuel Bernier) model published in 2012 on Thingiverse.
It's a great model and Idea that I wanted to share.

@Sam : If you see this and you want me to unshare, be free to advise me and I'll delete this sharing. As a designer, I fully respect your work !

An other cool way to reuse a Masson jar using an IKEA suspension kit and funky 3D printing.

Instructions

All you will need is a 3 inches wide glass jar (lid size), the 6$ IKEA suspension kit, a light bulb and this file.
Print the shade, the bigger opening facing the table. Set the support angle to 30 degrees. The part takes about 3 hours to print in normal mode. 0.25 thickness.

Then pass the cable trough the hole, screw the light bulb and then screw the cleaned jar. You got the lamp!
