Double-Sided Vacuum Block with Side Connection

Double-Sided Vacuum Block with Side Connection

Key features

• Double-sided sealed surfaces to clamp a flat workpiece on a flat table
• 4 different versions
  • Single port (e.g., as end piece or for single usage)
  • Dual port for daisy chaining multiple blocks (180° port orientation)
  • Dual port for daisy chaining multiple blocks (90° port orientation)
  • Quad port for daisy chaining multiple blocks (1 port on each side)
• Connection of the vacuum tubing from the side (other variants available as separate download, e.g., Vacuum Block for 20 & 19 mm Bench Dog Holes, Slim & long version, Compact version)
• Fits standard connectors for vacuum tubing
• Multiple blocks can be nested into each other (including the pneumatic fitting) for space saving, efficient storage

Storage solution available

• Compatible with the Loc Block French Cleat Holder (for 4 pcs)

   

Additional hardware required

• 5 mm foam seal (e.g., https://amzn.eu/d/6fLlTmm)
• PC6-01 pneumatic fittings (e.g., https://amzn.eu/d/0bj1HB2)
• Useful starter set including pneumatic fittings and tubes (e.g., https://amzn.eu/d/br2hIfl)
• CA glue for closing the foam seal
• Vacuum pump
  • I would recommend a strong version with 500+ Watts if you are planning serious work like clamping for sanding or routing. I am the using this one.
  • If you want to try it out and have a fun project, you can build the smaller Filament Vacuum Pump (this version will not able to drive more than 1-2 blocks but is great to create a filament vacuum for storage)

Installation instructions

• Print
• Screw in the pneumatic fitting (gentle force, don't over-tighten, keep it straight) - Important: This fit can be a bit tight depending on the output from your printer. Stop if you feel a medium/strong resistance. I heavily recommend to heat up the metal thread part of the fitting and the threaded hole of the block for a few moments using a heat gun or torch (really short, don't burn the part). After the heating the fitting should screw in with limited resistance. This will prevent potential layer separation (which otherwise might happen immediately or over some time)
• Add foam seals on both sides; recommended to cut the foam around 45 degrees before glueing together with CA glue to make a stronger joint
