Are you sad you don't have a way to mount extra speakers to your car boot?

Cry no more!

Fits almost all 13cm car speakers. The speakers from the image are Kenwood KFC-S1366

Needs 8x 4x25mm (4x30mm also work) wood screws. I used Cable ties to hold it as my car has a boot divider

Print in PETG because of car temperatures! Can also be printed in ABS or ASA
