A Twist Lock System for the Bottom of a 5 Gallon Bucket
thingiverse
This is a mechanism to allow you to lock a 5 gallon bucket down to a base. In my case, I use it for a mobile dust collector where the dust collection bin is a 5 gallon bucket, but I'm sure there are other applications. There are two parts - the "Pin" part is mounted to the bottom of the bucket with screws through the bottom of the bucket. The "Lock" part is mounted down to the surface you want the bucket to latch to. You will need (5) 1/4" steel dowel pins that are inserted into the "Pin" part. I used McMaster part #98381A537 https://www.mcmaster.com/98381a537 but any 1/4" pin should do. I used Cura's support offsets to make cleaning out the lock areas easier (by making sure the supports didn't touch the inside surfaces in that area). https://www.youtube.com/watch?v=wQgA4L-MKi4
