**Edit** - Use (v2) version as it is correctly sized vs. (v1) being slightly off. I also added a chamfer to (v2) to make it easier to insert into the roller. The last 3 photos show the (v2) version installed in the left two rollers with the last photo showing the printed part on the left and an original roller on the right.
My father-in-law has an expandable platform that handles long pieces coming off the table saw after they have been cut. It it essentially four legs on casters connected by a series of scissor joints that have a roller at the top. It's stable when extended but is quite top-heavy when it's collapsed. It got knocked over at one point and the plastic part that centers the roller on the bearing broke on one of the end rollers. I used this as an opportunity to learn OpenSCAD since it is essentially a series of cylinders braced with 6 radial fins.
I printed it in PLA on a CR-10 V3 at 200C/50C with default settings plus supports. The supports can be tricky to remove, I suggest using a pair of needle-nose pliers to grip them and then rotating.
The roller platform is sold under multiple brands so I thought this might be useful to someone else. I'll update with a photo the next time I visit and can install the part.
