5 Gallon Bucket Funnel Cap

thingiverse

I use these five-gallon buckets for disposing of used oil, but I couldn't find a funnel that fits the wide mouth well and won't tip while pouring dirty oil. So I designed this - it screws onto the bucket and has an integrated funnel with air vents to drain quickly. I also included the plain cap file if you need a cap or want to design off of it. This is designed to fit a 150x150x150mm print bed, and can be printed without supports.
