This is a simple 3D printing project to make a holder for an Intel Realsense D415 depth sensor. It can be affixed to a flat surface, maybe using 3M double sided sticky pads or glue, and the depth sensor is then simply slid into it.
I tested with my D415 and it seemed just the right size so as not to be too tight, nor so loose that it can easily slide back out in use. It was originally designed to be stuck onto a smartphone cover for quick point cloud creation, as you can see in one of the photos.
The D415 and D435 sensors are very similar so this design may work with a D435 too. However, in case you need to make any changes to the design, to cater for your own needs, the OpenSCAD file is also included here.
