Cantilevered bracket for your extra spool holders

This remix solves the center of gravity problem for the original model, and adds more screws to secure spool holders that fit the Mk3s top bar to on shelf or under-shelf applications.

When I put my Mk3s in an enclosure, the clearance for the original spool holder was too tight and larger filament rolls would scrape against the top of my 2'x2'x2' (feet) enclosure. That lead to replacements and then upgrades, leaving me with extra spool holder brackets.

Starting with a small bracket found here (remix attributed) I added support to the bracket, extending past center of gravity. This makes the spool holder bracket and mounted spool holder self standing, and takes a lot of strain off of screws.

You can mount above on a flat spot, or below a shelf. The low profile spool holder shown is best mounted below a shelf or off the edge of a shelf.

The whole thing is parametric - you can lengthen the bar all you want. I wouldn't expand the brackets though or they'll not fit the bar any longer.

Go with defaults, as is. I got the color change by pausing print.
