Hey guys,

You can print this and use it to tighten your vaccum tube. Find it here: 

This works with an M3 screw and washer as it's been easier to make for tolerances' sake.

First, you have push your screw and washer all the way through the hole on the holder and superglue it to the wall, so it can no longer turn.

Next, insert an m3 nut into the smaller extremity of the printed knob.

Once all the glue has dried, you just need to screw the knob into the exposed end of the screw. It'll tighten because of the nut inside of the knob and the fact that the screw head has been glued immobile. No need for monkey wrenches or screw drivers! :)

Cheers,

JR
