I created this guide for the ptfe because I have the AMS on the side of the printer and it remains lower, consequently the ptfe tube made a couple of bends that I didn't like. This model uses up to 4 6mm x 3mm magnets, I am currently only using 2 and it does not move, in case it vibrates there is the possibility of installing up to 4 magnets. The hole for the magnets is VERY PRECISE, to install them I used a piece of plastic and with a little pressure they entered the seat and no longer move! Made of PETG without supports.
