Got the parts printed for the frame and also got the frame built:

Had some issued with the extension parts, the black PLA I have (brand is bq) was oozing quite a lot and the prints weren't that clean. Haven't had that kind of problems before so going to blame this particular roll/brand of filament. Had to spend some time cleaning them, which could have been avoided by switching to another brand. Sadly don't have any other black PLA at the moment and didn't want to mix colors... need to order more.

Next, Y-axis parts. Ordered some stepper motors from Aliexpress, those probably take few weeks to arrive. Got some random leftover motors that I can use for test fitting, but I want a matched pair for the final setup.
