This mini ornament stand is designed to hold a 1.4 inch long ornament with a 7mm (millimeter) diameter internal hole along this axis. You can make your own ornaments using various materials, beads, or purchase compatible ornaments in this store.
The bottom tripod stand is connected to the rod part with a small sprue that you need to cut off. Connecting the two parts in this way reduces the cost by eliminating multiple parts handling charges at Shapeways. Cut the sprue with a pair of small wire cutters or a strong pair of scissors where the screw thread ends. You may need to sand this end smooth a little for a proper fit.
It is likely that residual powder from fabrication will be present within the screw threads of the bottom cap and you won't be able to screw the parts together until this powder is removed. An easy way to remove this powder is to slowly screw and unscrew the two parts together in a bowl of water or under a low stream of water from a faucet, rinsing out the cap between attempts as the powder is loosened. It only takes about a minute to do this and once the residual powder is gone the cap should screw flush with the main body of the hanger.
If you want a permanent assembly you can use a small dab of glue on the screw threads to keep the tripod in place on the rod body.
