CR-30 3DPrintMill Splice Extension Roller Sched 40

After printing a roller from the printable splice models I realized my roller was not very round and it took forever. Then my wife asked why I printed a wooden dowel. This got me thinking.

I got a 1 1/4" Schedule 40 PVC conduit from the hardware store. I designed and printed these end caps.
I cut the 1 1/4 pipe at about 9 3/4" in length.
They take 625 bearings. I ended up just printing the ones from here https://www.thingiverse.com/thing:2516471/files

I also made a CR-30 optimized version of this part so it prints better on the CR-30
