I have tried several versions of holding the driver tips

a few of my goals are:

1. mobile: I wanted to be easily take the set of tips away from my work bench.

2. I want them to sit on a flat surface.

3. if it is tipped over I want it to not dump all the tips

this take a while to print, with all the pauses.

the tips are held in with embedded magnets. 6mm Dia x 2mm tall. 51 magnets. I have one magnet holding in two tip

Lots available, one source is:

Because there are parts of head are magnetic, If you just put the magnet in it is sucked out. I got past that by putting a drop of supper glue in the hole. the spraying some accelerator on the magnet. Then putting them in the hole. and the supper glue activates on contact.

I used a razor blade as a flat surface to hold the magnet and put it in the hole put my finger on it to hold the magnet down. Then slide out the blade.

the print profile has pauses just before the cavity is closed off.

make sure you don't turn on support. no support is needed. you don't want the slicer filling in where the magnets go.

Where I am putting it I have 2 holes for M4 screws that go into my peg bord system. this makes it easily removable.
