About this 3D model

This replaces the cardboard enclosure that comes with the diy kit https://www.clasohlson.com/se/H%C3%B6gtalare-DIY-byggsats/38-8019-1 When you install the speakers melt the nubs and flatten them to secure the speakers. I think this kit is the same as the one Clas Ohlson sells https://www.ebay.com/itm/Thumbs-Up-DIY-Wireless-Boombox/192558938743?epid=754845205&hash=item2cd5683a77:g:TXYAAOSwkkNbFZZ7
