Boat trailer roller 180mm

thingiverse

I'm producing eight identical prints of these parts for my trailer using ABS material with a 5% infill setting, featuring four outer walls and four base walls, plus five top walls. The overall length measures 180mm, while the outside diameter is 65mm, tapering down to 55mm at the center. A hole, precisely 13.5mm in width, has been drilled to accommodate a M12 galvanized bolt. I'm using these prints at my own discretion for a trailer that will securely hold a 3.8m inflatable Zodiac-style boat equipped with a 15hp engine.
