I watch Watch restorations as I find them fascinating. I also like all the specialty tools they use. One I've seen several times is a simple little box with two sponges used to lubricate o-rings. Now, you can definitely buy these easy peasy, but what's the fun in that?

Shopping List

  1. 25mm thick sponges that are at least 50mm in diameter (I used these).
  2. 50mm round hole punch, or scissors and a steady hand (I used this).
  3. Use whatever you think the right lubricant is. I used some stuff that said it was for O-rings. 

Building the Tool

  1. Print out the halves.
  2. Cut out the sponges to roughly 50mm in diameter.
  3. Glue the sponges into their respective halves. I used hot glue.
  4. Apply however much lubricant you deem as being “enough”.

Using the Tool

  1. Insert O-ring.
  2. Put the two halves together and rotate back and forth a couple times.
  3. Extract lubed o-ring.

Printing Tips

  • Slice your own file for best results.
  • No supports needed.
