About this 3D model

STEP files available in “Download STL/CAD Files”! Mount speakers or other large items to the ceiling with this robust support. Easy and fast to print and really large! The custom designed joint is really solid and easy to assemble. Use the maximum size your printer can do. The interior space is 233mm(9") high and between 400mm(15" ¾) and 450mm(17" ¾) wide. 400mm(15" ¾), 420mm(16" ½) and 450mm(17" ¾) wide models are provided. You can mix two sizes to get intermediate width, e.g. print one 400mm and 420mm to get a 410mm wide support. Message me if you need different width or height. Use PLA Basic or PLA though. I'd recommend to avoid PLA Matte or Silk since they are more fragile. Printing Given the long length of the model, warping can occur. See the Bambu forums for tips to help with adhesion. If the joint warps, the assembly is going to be much more difficult. Reviews are appreciated! Had a failed print or you feel the model is not good enough? Please message me instead of leaving a bad review so we can work it out. Thanks! Boost Me I'm making my models freely available. While I often make them for myself first, it takes a fair amount of time to create pictures, print profiles and documentation so it's easy to print for you. If you find this design useful, please consider supporting with a boost (and feel free to leave design suggestions!). Thank you for the support!
