I have created simple angles of different lengths with which you can, for example, connect boards at a 90 degree angle.
I have uploaded them for you from 30 millimeters to 170 millimeters (in 20 millimeter increments).
Please make sure to print them upright, otherwise the stability due to the layers, if printed differently, will not be sufficient to withstand the loads that may be placed on the angled board.
Have fun with it!
