Front & Back Edge Clamp for Shapeoko CNC Hybrid Table (3D Printed)

How To Workholding
1

I have several upcoming projects that require 48.5" x 48.25" plywood sheets on my 4x4 Shapeoko 5 Pro CNC. I designed this clamp for situations where the stock covers the entire spoil board or is flush with the front or back edge:

The 3D Print File is available on Printables:

Specifications:

  • Stock thickness: 3-26mm (1/8" - 1") depending on spoil board thickness.
    • I created three different TOP parts to cover as wide a range as possible.
  • Stock position: 10mm overhang (outside the table) - 15mm inset (inside the table).
  • Hardware: M6 Square Nuts and M6 x 30mm Socket Head Screws.
  • Compatible with Carbide3D Hybrid Table (Shapeoko HDM, 4, 5, Pro).

3D Print Settings:

  • I used PLA with 100% infill for maximum rigidity/strength.
  • The bottom part does NOT require support. I added a sacrificial layer built into the model that can be removed after printing.
  • The top part requires support. For a clean and firm surface, I used PLA Support for the interface layer (PETG can work as support interface too). “Normal” supports are OK too!

And now, moving on with the actual project (fridge cabinet for campervan conversion)!!

Very nice! Thanks for sharing with the world as well :hugs:

For the top piece, if the bolt head isn’t inset could it be printed directly on the bed with no supports :thinking:

It could, yeah!
That would bring the bolt head a few mm higher, but it shouldn’t be an issue with clearance since it’s (in most case) outside the work surface.
Should I add a version without screw head pocket, as described?

Full disclosure, I won’t use it because I only have a nomad :melting_face:
I was just asking so I could verify my understanding and practice some 3d printing design theory :slightly_smiling_face:

Thanks for offering to put up an updated version though, that’s a kind thing to do for an internet stranger :beers:

Gotcha!
Supports are fairly common in the 3D printing world, and they work especially well with PLA :slight_smile:

I wouldn’t mind a set of these. I’ll have to see if I can find someone local with a 3D printer.

I recently had the same need to I rigged these up…

You should sell and ship these. I’d buy a set!
