This is a super simple fast print, It's a simple open air stand for bluetooth module and amp board. The idea is to use separate speakers and to be used as a mini bookshelf system.

Bluetooth module like: https://www.amazon.com/Bluetooth-Decoder-Decoding-Support-Lossless/dp/B07S51R6V1?crid=2VF8EUX6MGGWI&keywords=bluetooth+module&qid=1675115411&sprefix=bluetooth+module,aps,160&sr=8-49&linkCode=sl1&tag=bbtech0db-20&linkId=90e8eab2bab5908473ed1e9e1adb0684&language=en_US&ref_=as_li_ss_tl

amp board kinda like this: ???

I see Thingiverse still likes to butcher Amazon links so .... https://www.printables.com/model/384811-bluetooth-radio
