Summary

I tried to print a tool to remove the gear on a motor shaft (remembering to have seen one but can't find it again)...

But that didn't work (contrary to hammering it with an M4 screw while safely holded in a vice).

[edit 05/11/2012] Just use a vice : http://youtu.be/pT2zk--KqBo

[edit 01/06/2012]
Now may work :)

Print, try and tell us if that worked, or improve it, make it work, and share the lesson :)

I tried all sorts of gear pullers without success,  ended up clamping the gear in a vice and using a punch on the drive shaft to separate the two parts. Couple of taps with a light hammer and the gear is of. 

 yeah the same here :)

I printed one in "High Impact PLA" from Diamond Age, and it delaminated very fast under use - see photo in the "U made one" section.

Maybe I do not master the printing settings for that plastic then.

Anyone had success using this ?

erf too bad it didn't worked : /

Maybe avoiding layers detaching would be possible by adding 4 bolts all the way through the corners of the "cube", perpendicular to the layers ? Might need to fatten the walls a bit to achieve that then.

I was thinking of designing one of these just today - for exactly the same motor!

Do you mean mine? http://www.thingiverse.com/thing:22417http://www.thingiverse.com/thi...

You really need to print this sort of thing the other way - so that the main forces are not trying to delaminate the object. I only got mine to work printed the way shown on my thing, and even printed at 100%, I only got 5/6 of the pulleys I wanted off, and broke one puller in the process.

Nut puller

haa thanks ! I didn't tried the right keywords :)

(and after looking at the pic I also tought it might be printable on the side like yours)
