Need to break off the support material on the bottom, but looks promising!
would it be rude or ignorant to ask what that is?
ohhhhhhhhh ok
It is a 3D printed bearing made in one print. If the bottom turns out well, the balls inside will spin. I need two of these for my next project. I plan on having a shaft/arm through the center of them. The arm should rotate freely. Very slow rpm so plastic should be ok. It is an experiment at this point.
wow thats pretty intense. may i ask what the projects all about?
Sure, if it works… It will be part of a satellite tracking antenna system. Ham radio stuff. This bearing will be part of the arm that moves the antenna up and down. Project is still in it’s infancy.
Good luck. These always turn out more art than function for me.
I’m on a team for the First Tech Challenge, it’s a series of robotics competitions, anyone have a suggestion of parts for me to 3D print?
Great print, good design, but I don’t think that making a ball race bearing out of plastic is a good plan. It will be prone to failure, when a proper steel bearing can be had for a few dollars (or steal one out of a skateboard). You will not be able to improve on this technology.
You have the talent to make 3D objects and get them to print successfully. That is half the battle. If you are making a satellite tracking rig, then there will be ample opportunity for all sorts of mechanical links and mounts to be designed, printed, redesigned, improved and reprinted. This is the strength of 3D printing. Not creating that, that exists already, but making things that you could not easily obtain, or would be too expensive to machine using traditional methods.
You have made great start, keep up the good work, and hope to see the finished machine soon.
Lol, your heated bed is literally a bed? 
The skirt didn’t stick though.
