BSP-D11 adapter for Controller & Headset Stand

Simple adapter for Universal Controller + Headset Desk Stand by TheNerdyTwitch for a BSP-D11 controller.The stand (with adapter) can be used with or without a tablet/phone. I use it with my 10.8" Huawei MatePad Pro. Just glue is in the controller slot. I also added a 2mm foam strip (EVA foam) to have a more snug fit. 3MF profil contains a 51mm large version; 3mm larger than the stand dimension; I made it on purpose in order to avoid the controller to rotate when placed on the stand. But I also provide as a STL a 48mm large version.
