v-slot extrusion joiner Perpendicular (20x20 to 20x20 - - - -20x20 to 20x40)

This is a 20x20 v slot extrusions Perpendicular joiner to join 2 pieces tightly together at 90 degrees. There is a version with 2 teeth to be used for a connection between a 20x20 and a 20x40 extrusions or 2 20x20 with another 20x20 depending on the use case. The long ones might take a bit more time to print but they are easier to be fit in place(more that the short ones since its a tight fit). You might need to mirror the v-slot-joiner-90-long-20x40 since it is directed to the right. in the images i used the v-slot-joiner-90-long and v-slot-joiner-90-long-20x40 and in the middle of the two long 20x40s i use https://www.thingiverse.com/thing:7323504 Supports are recommended but not required especially if your printer is well calibrated . As for print orientation , just make sure that the middle beam is not printed horizontally (since layer lines can be a weak point). Feel free to edit the model to fit your needs.
