Coat Hook

I recently (temporarily) changed offices at work, and with the new office came a new door, and this door has no coat hook! Because I couldn’t drill a hole in the door or mar the surface in any way, I needed an “over the door” style coat hook. Ah yes, the classic coat hook. Adrian Bowyer made one back in 2008, so I decided it was time to make my own.

OpenSCAD Coat Hook

I took a quick measurement of the door to determine how wide it was. I then fired up OpenSCAD and made a bunch of “cubes” of various shapes and sizes, some rotated 90 degrees, but all in all, a pretty simple OpenSCAD model. One thing I did do was add in the “door” based on the measurement I took, so I could see how the coat hook would fit around it.

Plate Coat Hook

After compiling it in OpenSCAD, I exported the STL file, and at this point I usually use Gary Hodgson’s STL Viewer to take a quick look at the file and make sure it’s oriented correctly.

G-code Coat Hook

After viewing the STL file, I use Slic3r to generate the G-code, but hey, let’s check out the G-code while we’re at it! Joe Walnes wrote a great web-based G-code viewer you can use online, or download and run locally. If you want a somewhat improved version, Jeremy Herrman’s got a viewer and some code for you.

Working Coat Hook

Well, after all that generating files, and viewing files, I printed the file. It worked out well! Here’s a terrible photo of it preventing my shirt from falling on the floor. Success! The magic of a home 3D printer pays off again.
