Overview

This is a simple mounting adapter that lets you securely attach a threaded device such as a magic arm to a table or desk using a readily available, inexpensive C-clamp.

Usage

Thread the mounting device into the adapter. Clamp the mounting adapter to the desk or table using the C-clamp.

MMC Library Listing

If you need to add a furniture-saver pad to the C-clamp, this Parametric Wood Clamp Foot Pad with the following OpenSCAD parameters:

footOuterDiameter= 22;
footWallThickness= 3;
footWallHeight= 7;
footRetainerHoleDiameter= 21;

prints quite well in PETG and is a snap-fit over the end of a Bessey 2" C-clamp.

@SRv OMG this is so clever. Great hack! :clap::clap:

We’ve had a few reports of these failing after being used for a while. To some degree, this is expected from a 3D printed part, but there is almost certainly an opportunity to optimize the design.

The print file and original Fusion 360 design file are available on Thingiverse: https://www.thingiverse.com/thing:3541114

It would be great to have a maker look at how we can optimize the design and/or print setting to increase the durability of this part.
