That was an awesome video and project. Nicely done.

How do you get the rollers perfectly round?

Is it possible to get the step file for the small 10 roller bearing?

I recommend to load the f3d-file in Fusion 360, adjust the parameter, and then export it. Fusion 360 is free to use as a student or hobbyist.

Thanks for a great build, I downloaded the one with 20 roles.
Never used parameters in Fusion, took some time to find the option.

I printed and asempbly it without changing any settings and with with 0.2 layer height.
I think mine is a bit loose, it's like there half a role in space.

Another think I think would be good is to have the inner and external diameter as a varierbar, wouldn't it ?

Edit: On the 20 role I manged to add a inner but it was harder to add the other using a Press pull feature.
I added 2 variables OrgInnerDiameter and InnerDiameter, the value on the Press pull was (OrgInnerDiameter - InnerDiameter) / 2

On the version 2 I managed to add both inner and outer in the same way, just different outer variables.

Great design and well explained.

I have modeled one myself in SolidWorks, and printed it in PLA, but I feel the rollers do not want to roll that well. The coefficient of friction is too low compared to the irregularities of the print surface. What's your experience?

I can only guess. Maybe the rolls/cones are not round, or they have uneven rough surface? Maybe there is not enough space between the rolls? Maybe the rolls are too high? The rolls should touch the races only with the rolling surface, top and bottom of the rolls need to be flat and smooth.

Is the Top and Bottom Race the same part?

What is the diameter of the screw holes?

3mm. The diameter and the number of holes are adjustable by two parameters in the design.

Thanks a lot. Looks like a perfect candidate for my 3d printed biomass shredder project !

One of these with an 8mm center hole would be nice. Other dimensions not too critical.

brilliant design & tutorial. great job!

Great design and well presented video, outstanding work!!

Any way to get this converted to an SCAD?

I guess it's not possible to automatically convert it. A re-design in SCAD is certainly possible, and probably not very difficult.

Is there a reason why you put the whole in the cylinders ? They look allot like one of those candy necklaces.

there is no specific reason. but they are useful for handling, because you can push a rod through the hole. for removing from build platform, for sanding, ...

Aha ! I realized when i was putting mine together :).

Really nice design ! I will follow your tutorial step per step when i get the time for sure ;). Always fun to mess around with parameters !
I find the way you designed it to be more efficient vs how i would do it, so i certainly will learn a few things doing so.

Thanks for the great Tutorial!
