SC8UU replacement for IGUS Drylin RJ4JP-01-08 (LM8UU)

I wanted to upgrade my LM8UU to IGUS Drylin.
First attempt was to just swap LM8UU in the existing aluminium SC8UU by IGUS Drylin RJ4JP-01-08.
Result was a lot of bearing clearance.
According to datasheet, the IGUS drylin bearings need to go to a percision machined hole setting a certain preload.

I looked for some printable SC8UU replacement with possible good preloading / clamping.
Found nothing applying force on all circumference. I didn't just want to clamp the IGUS drylins in one direction.
Here is what I came up with.

Already in place for the X - Axis on my Anet A8; no play in X Axis any more.
Can be adjusted by mounting screws.
The four in the picture are to go to the Y Axis.

Needs 4 screws M4x25, a nut M4 and a IGUS Drylin RJ4JP-01-08 each.

Can be combined with printed bearings also:

Original inner diameter is 15.1
Just added two more stl with inner diameter 15.5 and 16.0 - untested and not yet printed. Choose depending on your printer tolerances.
