Installed new speakers on my ski and needed an adapter because the OEM holes are different than most aftermarket speakers. Model is available in 156mm and 157mm spacing depending on the speakers you use. I used M4 heat set inserts placed from behind to mount the new speakers to. Use M4 16mm to mount ring into OEM holes. Model fits snug. Best printed in ABS/ASA but can be done in PETG as well. Recommend 6 walls and 25% gyroid for strength.
