Description

Miniature hand drill.

I was in desperate need of a small chuck/hand drill to hold onto some 0.6/0.8/1.0mm drill bits to clean out some holes but couldn't find a place the sold them for a decent price. Holding and placing such small drill bits was a pain, so I quickly modeled and printed this as an emergency/temporary measure.

Works well enough but lots of areas that can be improved. Might make this parametric later...

oh and BTW, I totally forgot to print the drill holder flat, so my prongs broke. :)

Instructions

FDM Printers (Up!, MakerBot etc) : The drill bit holder needs to be printed 'FLAT', otherwise the piece may be too fragile and break as the prongs are bend together. The layer boundaries are weak and may shear through if printed 'TALL' on a FDM printer.

The other two pieces are printed tall. The support structures for the threads are easily removed by simply removing other attached support structures and unscrewing.

The pieces feature a M10 thread, so 0.2mm and fine settings are recommended.

//Tested on an Up!. Not tested on a MakerBot, volunteers welcome!

Awesome, but it needs a one-way threaded "pump" handle so you can drill without turning the thing by hand.
Also known as a 'Pin Chuck'.

Nice.
Ahah! I was struggling to remember it... [and obviously failed].
Cat's out of the bag, I have a pen-sized motorized version using a small geared motor I will upload ... soon (tm).
Did you have to thread the parts after with a tap an die or does the Up print that accurate?
Just thought I'd add another data point. I printed this on my UP! printer, pulled the parts off, and screwed them together without any cleanup required. Totally awesome.

Did not need to tap at all. Worked out of the printer after removing the supports. I did originally have problem when the wall was too thin and the outside of the wall looked horrible. The uploaded files print as per the pictures with no after finishing.
Thats amazing.
Probably not. The up is really really good. Especially if you take the time to calibrate it properly.
