ANNEX SMART POLES

Got sick of Setting up my annex on my camper trailer. Came up with this to put on the end of poles. Join poles together and have them on a hinge.Have included different types as I'm not sure which way I'm planning on going but they are all available. Printed in PETG, 60% infill and 8 walls.Can do more/less guessing want this as strong as possible.The push in pieces, I lowered them down and printed them in 2 halves and glued them together. Didn't need supports this way.
