HSW Magnet Holder

HSW wall holder to work with the labelled caps and tubes built from https://makerworld.com/en/models/938361#profileId-903648. I went with 5 slots because that's what I have a need for currently. Manual tree supports are included in the profile to handle bottom of the upper insert. I used three inserts in case you fill it up with some big boys and the tubes slide in with nice tolerances.
