We want to incorporate the Startech industrial USB hubs into our advanced astronomy equipment. We are working inside some tight enclosures and wanted to know if there are CAD files available of your outer enclosure dimension, showing port locations and most importantly, mounting hole locations and exterior dimensions. Your specs don’t seem to show the mounting hole centers, unless I’m not seeing them. We will be making CNC aluminum enclosures and knowing exact dimensions is helpfull. thanks, J.G. ---

Hello @jeffdda, Unfortunately we are not able to provide a CAD file for our USB hubs, however I am happy check if we may be able to provide a technical drawing that has the dimensions and mounting hole locations you are looking for. In order to look further into this for you, can I please ask for the following: - Can you confirm the Product ID of the specific hub you are referring to? - Do you know how many units you have or would be using? I look forward to hearing back from you. Lukas T ---

Hello Lukas, I have the same question, but regarding 3D CAD data for the open frame racks (specifically 4POSTRACK15U). Thanks in advance Zoltán ---

Hello @LukasT I’m in the same situation. Went to the product page [https://www.startech.com/de-ch/server-management/4postrack15u](https://www.startech.com/de-ch/server-management/4postrack15u) but couldn’t find CAD files for 4POSTRACK15U. Is there a possibility to download CAD files from somewhere, preferably in STEP format as they will be used in FreeCAD and the rack will become part of a larger FreeCAD Assembly Workbench project? This would be my preferred way as I don’t want to measure and re-draw everything myself wasting many hours. ---

Hello @siodor, CAD models are generally not available publicly, but we may provide them in some circumstances. Should you require one, I would recommend submitting a request here from your work e-mail, outlining why you need the CAD model, or advising if a 2D drawing will suffice: [https://www.startech.com/en-ca/support/form](https://www.startech.com/en-ca/support/form). And from there, we will investigate what we may be able to do to help. Sincerely, Lukas T
