Sandpaper Adapter for Oscillating Multitool by p1mrx
www.thingiverse.com
This is an adapter for holding sandpaper with an oscillating multitool. I designed it for a DeWalt DCS356, but it may fit other brands/models with the same blade interface. The Everclamp grid with sqwasher plate and thumbscrews lets you attach sandpaper, a sponge, or other irregularly-shaped objects in any orientation. Do not print the "uncalibrated" STL files, as the threads will not fit. Instead, use OpenSCAD to convert the attached *.bundle.scad files into STL, calibrated for your printing setup. See https://everclamp.org/#calibration for instructions. PrusaSlicer settings: Layer height 0.2mm Gyroid 15% infill The elevated flat part requires good support to print correctly: Support style: organic Don't support bridges: unchecked (in other words, DO support bridges) Overhang threshold: 10 degrees (support the bridge, not the screw threads) Top/Bottom contact Z distance: 0.2 (detachable) Top/Bottom interface layers: 3 (heavy) Support speed: 20 mm/s (slow)

In other news, if you try to upload a file named uncalibrated_example.stl to Thingiverse, it fails with no error message, because somewhere they have a pr0n filter searching for rated*x.

Some people might find this bundle_scad.py code useful. It combines an STL, SCAD, and all its dependencies into a single file.

    That is interesting. I’m professionally curious about the drive mechanism for the oscillation pattern on these now. As a former auto body shop owner and painter, I would not expect this to be free of mechanical error like a high quality pneumatic dual action sander, but it is an interesting idea. In fact I can imagine taking this to another level and creating a thin sanding blade like design with Emory paper, to use in very tight slots.

      Does mechanical error actually matter when using sandpaper? It seems like most of the error comes from holding the tool with your hands.

      You can buy these from Dewalt with triangular shaped velcro backed sanding pads. I used one to refinish a crappy bedside table during covid and it did leave a lot of weird sanding marks (especially if the paper picks up any debris) but it does work. It’s probably better suited for small surfaces that aren’t flat.

    What material did you print this in? Sanding generates heat pretty easily and may soften some materials. I’m curious of your experience with that as you’ve given me some ideas for sanding jigs.

      PLA, but I’ve only used it for sanding small models so heat wasn’t an issue. PETG should be more heat resistant.

    I don’t know how to tell you this but this already exists. Get a Oscillating Multi tool pack at the store and it comes in all of them. I have three different ones.
