Single U groove roller top

I felt uneasy how the puller cable is routed over two flat bearings. After searching for suitable bearings it appears  those are either not so common or reasonably expensive, so I designed my own U grooved roller to use the BOM F695 bearings. Instead of two bearings, there is now a single larger roller on the top. This required redesign of the top part to be taller.

To assemble use the M5 bolt from the BOM and two of the F695 bearings. You can also use plain non-flanged 695 bearings. The original printed spacers are used a well.

You might want to print the roller with 100% infill (I did with 40%, is ok) and also with the accent color. To fit the bearings I used a vice.

Replaced the top part to use single larger U grooved bearing, instead of two small flat bearings.
