If technology had allowed it, the coded mask of the ECLAIRs instrument might have been made in 3D printing. But what was not possible for the real flight model is possible for a model. So here are the STL files allowing to manufacture a replica of the coded mask in ¼ scale.
The STL files have been adapted from the CAD (computer aided design) of the original model to allow a scale ¼ printing in good conditions : The plate thicknesses were slightly increased to accommodate the capabilities of the printers and some small parts were either merged with the main parts or simply removed.
In practice, the 4 files correspond to the 4 parts shown in the figure. As the real mask is made partly of titanium, partly of tantalum, it can be of the most beautiful effect to print the tantalum part in one color (ECLAIRs_Coded_Mask_FM1_Tantalum) and the rest in another. Don’t hesitate to send pictures of your realizations!!
Many thanks to the APC laboratory team for supplying the CAD model and to Aubin Guillemot for his work in adapting the STL files.
