About this 3D model

I have adjusted the tube size to 75cm and added a 90° elbow, which makes it better compatible with PU steel wire hoses. Also, since I don't have a 10mm magnet on hand, I have adjusted the magnet to 15mm*2.5. Using BING3D's PETG LS for printing, 220 nozzle, 40° heated bed is sufficient. Because the mortise and tenon joint is very tight, you can even skip the magnet.
