Featured Thing!

Description

I made these for drilling out holes in 3D printed parts.

I am not sure if bushings would work all that well, but it might be worth an attempt to find out.

And as to your comment about two nut traps not being necessary, I am only doing that so that the drill bit is clamped between two pieces of metal, not metal and plastic. It also helps to center the bit. You can change the number of nut traps in Customizer and/or OpenSCAD as well.
I said it in my make, but i feel maybe i should say it here too. Trivial as it is, probably a good idea to add a cylinder with holes at the right place so you can print a big one and use this cylinder to make small ones fit well.

I had a rather silly approach to holding in a bit. Just use a screw, d'oh.
BRILLIANT!!!!

Instructions

Open in Customizer.

Input the dimensions for the handle. Note that if you have drill bits measured in inches, you will need to change that at the top and then input your diameter AS A DECIMAL.

Print

Insert Nuts into the nut traps

Insert the drill bit

Insert set screws. You should be able to tighten them a lot, but do remember it is plastic.

Also
It appears on my computer that there is an issue with rendering the handle in Customizer. It cuts a small chunk out of the lower groove. It only appears in Customizer, however, once you export it as an .STL, it goes away.

This is a fantastic idea.

Have you considered designing it with a T-Shaped Handle?
Or maybe design an accessory that docks with your current design...

I think It would be easier to use.

Great job!!! ;)
I have run across a number of screwdriver shafts with no handle for which this would be good.
A really useful tool. I've made it my Thing of the Week on my blog, 3D Genius:

Thanks for such a great job!
Im going to make a slight adjustment and then reupload this if thats ok
i think i have a way of making it better
nvm what im thinking wont work
Just what I need to clean out the holes on my prints. :-) I never want to use a an electric drill because it seems like overkill.
