Stanley Hobby Vice - Watch Jaws

3D printable replacement jaws for the Stanley Hobby Vice which is available in Australia from Bunnings Warehouse.

Not sure if an equivalent exists anywhere else outside of the Oceania region.

Jellybeans

• 8x M4x4.0 CNC Kitchen threaded inserts (melt ins)
• 4x M4x15 fasteners ^
• 4x M4x10 fasteners - To replace the low quality fasteners provided on the metal jaws…
• Thick walled silicon tubing, approx 4mm id ^
  • 4x pieces of 10mm lengths ^

^ I'd consider doing this with longer fasteners and longer tube as for my watch the fasteners are close or touching on the watch which is less than ideal.

Jaw fastener center to center dimension: 42 mm

Jaw fastener vertical offset from the top of the jaw face: 9 mm

Instructions

1. Print 2x of the watch_jaws-i1_38mm_v3.stl files
2. Use your favorite method to install the heat set threaded inserts
3. Remove existing jaws from vice
4. Throw out the poor quality fasteners that came with the vice
5. Replace said fasteners with new higher quality ones (the M4x10 ones)
6. Cut 4x 10mm long lengths of thick walled, 4mm inner diameter silicon tubing. You can vary from this accordingly, just ensure that you change out the M4x15mm fasteners accordingly
7. Screw into the jaws until the silicon tubing is slightly deformed.
