A hub with sockets for round tubes or dowels, to build a frame, a shelf, a greenhouse or a tent from lengths of tube: straight to join two lengths, an elbow, a tee, a three-way corner or a cross.
Enter the tube's outside diameter. The clearance is added to every socket; 0.2 mm gives a push fit that holds without glue in PLA, 0.4 mm a fit that slides and is glued. The socket depth is how far the tube goes in, about its diameter or more for a frame that carries a load. The outside is square, so it rests flat on the bed and on a floor.
Print it as shown. The upward socket is printed as a straight tube; the sideways sockets are horizontal holes whose top is bridged, which prints clean up to about 30 mm and sags a little above that.
