I designed this heavy-duty cup holder in Fusion 360 because standard mounts can't handle rough ATV trails. They always rattle loose or break. This model is custom-engineered to lock perfectly into CFMOTO mounts with a reinforced dual-wing base (26mm diameter / 41mm length). The interior requires zero supports. Printed flawlessly in PETG on my Bambu Lab printer. Built to survive the mud and trails!
