Hi!

With this 'hooks' you can replace easily a spool on a wall mount.

I saw this 'hooks' on Youtube Channel 3d Printing Proffesor but i didn't found for printing so i made my OpenSCAD customizable version.

They are extremely useful. Replacing a spool for the wall mount is a pain and many times can be dangerous.

I've include 2 files that i'm using. They have a 28 mms pipe for the bar of the wall mount and a 30 mms tube for the spool. They are for 1 kg and 750g spools.

The customizer it's easy to use: There's a picture with the parameters used. Just take care of diameter of the rod used on the wall mount and give 1 or 2 mms tolerance. They don't need to fit exactly.

There's a 'pin' on the spool side for connect with other hooks and give more 'strength' to the whole set of spools. Really don't need but i decided to keep as an optional part.

Hope you find it useful. For me it's one of the most useful things i've printed.

Have fun!
