A friend of my wife has buisness that sells necklesses and bracelets. She needed something to diplay them on, so this is what I made for her. It is desined to use a 1/2' dowl or alum pole for a riser.

Print all the files. Sorry the plates are set up for a Mendel size build platform. I will include the sketchup files if anyone wants to break it up smaller.
Assemble all the parts and injoy. I used a m3 x 16 bolt with two washers between the cap and the top wheel to connect the wheel so that it spins.
I made one of these for my daughter and added a her initial (K) on the center of the top handle. It looks very cool and she liked it alot.
