STL Simple Viewer

I frequently had the problem that downloaded STL files needed some minor editing in order to be printable on my 3D printer. Most of the time it was just a simple move to the center of the build platform or a resize. In addition to that, I already wrote OpenGL code to visualize STL and GCode files a couple of months ago for another larger project. Finally, I had sometimes a problem that I downloaded an ASCII encoded STL file and wanted to open the file in my 3D/CAD application. Since this application can only read binary STL files I needed an easy way to convert ASCII STL to binary STL. So I wrote Pleasant3D, a small utility that solves these problems and uses the above-mentioned visualization code to display STL and GCode files. This version implements better error checking in the Quicklook plugins and falls back to displaying the standard document icon if the Quicklook generation fails. That way quicklockd doesn't crash anymore in case of problems.

Binary and ASCII STL files, 3D viewer models for Android. Show support for multiple files/models. Practical view modes: shaded, wire model, shaded + wire model, points. Front and back are highlighted with different colors highlighted. Fast loading of STL files/models. Support for large STL files/models (million triangles). Binary and ASCII STL files/model formats. Mains boundaries/edge detection. Separate (not connected) networks/parts detection. Selection function (hold a finger on a model to select it). To deselect a model, hold a finger on the background. Show bounding box information in the status per selection. Invert normal in a selected STL model. Delete a selected STL model from the scene. Open STL files directly from Gmail attachments, Google Drive, Dropbox, OneDrive via Fast STL Viewer. 3D printing with Treatstock option. The app's internal file manager tracks 10 recently opened files for easy access.
