45 Degree Table Saw Jig Thing

This is a tool i made for a friend.
The challenge was to fabricate picture frames on a table saw.
To make the frame, it was necessary to cut 4 pieces of wood under an angle of 45 degree.

Therefore, a Holzmann table saw was used, but the included angle jig (i'm not sure whether this is the correct word for this!?) was really not the best tool.

So i made this thing in Fusion 360 and printed it on an Anet A8,
it took about 17h, if i remember that correct, so i used a brim to prevent warpi
