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.

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

      It does matter for automotive-class perfection. You will have hot spots develop that dig deeper than the rest of the surface. We are talking about mirror gloss perfection though. You are likely not working on a project of this scale/class.

      Patterns can emerge from resonant frequencies (https://www.youtube.com/watch?v=wvJAgrUBF4w). The dual action of a “DA” sander is made to cancel out the resonance.
