These are the .STL files of the first Daniel Christiansen bearing that I made. This is a specialty application design not for use with home 3D Printers. Very difficult and I have not came out with instructions for their assembly at this time. However, I have a tip below.
PLEASE READ BEFORE ANYTHING.
Beware: This is NOT designed for use with your typical FDM printer. I highly recommend not doing anything with these files other than to look at them. The tight dimensions found in this model produce difficult overhangs and the tall skinny towers within the Spacer Rollers are highly susceptible for knocking over. This model was designed with the laser sintering process in mind which provides ample support material and which can be removed as a powder.
Moreover, some of the functional surfaces of the models are slightly oversized in order to attain a snug fit after sanding. Once again, the laser sintering process of nylon creates a different material which is much easier to sand. If these models were to be created on PLA or ABS I am afraid it will be very difficult to sand correctly.
Not only that, but this is an alpha stage design, and also one of my first which I made years ago. This will have many flaws, one being the diameter of certain portions of the spacer rollers being too narrow, and also the main/small screw should have a different thread orientation and the hexagonal hole to be made round to achieve desired effect. I do not have the CAD files to this, so this will remain an alpha stage project FOREVER.
------ Important: I also do not provide instructions for assembly at this time. Only download this right now if you would like to figure something out on your own until I release instructions for assembly. To give you a brief tip, use a rubber band to hold the load rollers and spacer rollers together onto the inner sleeve in the appropriate fashion on one side, allowing the other side to be placed into the outer sleeve and reverse knuckle half sleeves. It is too involved to write about it here at this time.
With that being said, I have made these files available for those who wish to observe them, or those who have access to the appropriate facilities in order to create this bearing.
