Greetings all; I'm in a try it mood this morning while I wait for it to warm up enough I can go move some dirt in the back yard to make a level place to put a slab of concrete for a small plastic shed I bought to keep my new last year, rider in out of the weather.
So I've downloaded a bearing maker from thingiverse and have modified it to make a huge bearing that will fit around the outside of the moving spline. I had to cut the brim setting down to 2mm just to get it to fit the build plate width of this dremel printer, but it is building now, just to see if it will actually work. Takes a bit over 6 hours. The next roadblock qestion I'll have to answer yet is will it fit inside the alu I bought for a housing. if it will, I'll make another somewhat smaller one for the output end of the shaft. Pix from openscad shrunk by gimp attached. Here, "ball" is false advertising, the races have a raised ridge in the center, which fits in the "handle" area in the middle of the dumbbell shaped bearing roller. If it doesn't work, shrug. But its building now for the next 6+ hours. And I've another roll of PETG near in case it uses all of the remaining stuff on this spool. It seems plate adhesion is better if the machine is kept warm for a while before its actually allowed to start the print, so I warmed it up, verified the level & generally killed ten minutes. Seems to have worked. Translucent PETG, 234C nozzle, 77C bed, stick glue. Arthritic fingers crossed. Take care and stay well everybody.
