I love my Panavise Jr. I’ve used it to hold just about anything you can imagine and it always works like a champ. I do however have one small complaint, it takes forever to open and close. The threading on the threaded rod that opens and closes the jaws is very small and so it takes (approximately) between 2 and 3 million turns to move the jaws from fully open to fully closed.

I've solved this problem by creating a drill bit that fits over the crank handle of the Panavise Jr. that allows for quick opening and closing. Panavise has released a similar manual version of this but it's hard to argue with power tools.

More info and the evolution of the drill bit are on my site here: http://thenewhobbyist.com/2011/11/panavise-jr-speed-winder/

And a video showing it in use can be found on YouTube here: http://www.youtube.com/watch?v=JVQegeAXqLA


  1. Print "Speed Winder"
  2. Load into your drill
  3. Save minutes/hours/days of time previously spent opening/closing your Panavise Jr.

Aww man, I should've searched before I designed my own

Great job! One question, how did you print the 90 degree overhang where the bit meets the winder? I'm new to 3D printing and after studying the model and video (several times) don't see the trick? Do tell.

This model prints from the bottom up. So when it gets to the "top" of the winder it creates a flat surface and covers the hole the the top of the winder. Then it begins printing the "bit" section of the model.

Someone should modify this to make a speed string winder for guitar or bass. A little more torque may be involved, but shouldn't be hard.

hahaha nice video, panavise should learn from dremel multivise :P
