Description

A low profile clamp for securing wood and plastic to a CNC router's wasteboard while still having full access to the top of the stock.

There are two version of this clamp, which differ based on how the the threading is added. This version uses a threaded insert that is pressed in by a soldering iron. The insert has a flange on to prevent it from getting pulled out of place. Compared to the second version, which uses a hex nut, the heat-set insert model can be tightened harder for further clamping force.

The clamp is secured through M5 bolts, and therefore, your wasteboard must have threaded insets (like these: https://amzn.to/2TunKBK)

Model fits within a 135 x 35 x 25mm volume.

Materials required for assembly: -1/4 x 1-1/4" Metal dowel x2 (https://amzn.to/3g4d2th) -M5 Het-Set Threaded Insert (McMaster-Carr: 97171A350) -25mm M5 Bolt (McMaster-Carr: 93070A129)

Equipment Required: Soldering iron for putting the heat set insert into place

3D Printing Settings: -Can be printed without support. Highest infill possible is recommended for rigidity.

The Toe clamp pairs wells with the Universal Right Angle Jig

I know it's a long shot, but yes, please. I'd like a hex nut version that accepts 6mm pins instead of 1/4". I have tried modifying the STLs in OpenSCAD, but it's very hard to match the angles to insert a reducing sleeve into the existing holes.

Or if you could release the source as OpenSCAD, or a dimensioned drawing then that would also be good. Thanks.

I tested it with a 6mm dowel and it was still a snug enough fit to operate properly!

I haven't tested it yet, I placed an order for a 6mm aluminum dowel and waiting for it to arrive. Just wanted to be on the safe side when it arrives :)

Have you tried a 6mm dowel with this design? It's pretty tight fit for a 1/4" dowel and should work for the 6mm. If not, I can upload another iteration of this design.

Thanks for sharing the file!

Are you able to upload a version of a 6mm diameter metal dowel? It's a bit hard to find it in inches size where I live.

If you can upload the Fusion 360 file it will be great, I can edit it with no issue :)

Thanks!
