Gazebo 3 and 4 pole replacement parts

This repair part was done for a friend.I've updated to include a 3 pole part, its a quickly rehashed part, but should work okI've included a 3 pole version with reinforcing fillets on all sides.The 4 pole v2 is a version of this part that is completely hollow at the intersection, it saves filament and prints approximately 1hr quicker according to cura compared to the original.I'll leave the original on as it is probably a stronger part. These are made for a pole diameter of 20mm, the hole is 20
