I'm looking for right angle gearbox, but everything is horrible expensive or in parts like two bevel gears from aliexpress. Where I can find or how to name transmission like this in the picture but in box case (if possible with mounting holes)?

I need right angle transmission 1:1, no matter what type of gear or something else. Looking for compact size, outer size of one arm, max 40mmx40mm. Maybe I don't know proper name to find it.

Also if I don't find good out of the box solution, how to proper design that type of transmission? I know I need bearings on shaft and screw, but how to avoid skipping on teeth?

Your terminology is correct, but also sometimes called bevel gearboxes. A cheap off the shelf unit is a few hundred dollars. If that is too expensive you probably won't save any money designing and fabricating the gears and housing yourself. A u-joint is a cheaper alternative.

But if you are intent on making your own, Boston Gear has good catalogue parts and resources. KHK gear also has good technical resources online.

these things are sold cheaply (less than $20) for bending the output of an electric drill through 90 degrees, so you can drill holes in cramped places. they can handle from 1/4 to 1/3 horsepower typically. hardware stores sell them. they are called right angle drill drive attachments.
