Bicycle Chain Lube Oiler
I made it smaller to fit a bicyle chain (although I kept the length to catch the leaking oil better). I also made the sides thicker and stronger and added lips at the end to catch the top so it won't slide out when being used.
If you don't have three hands and you're using a flexible pipe, you can masking tape it to the frame to hold it - although I've found that if you slide the top on TOWARDS the pedals and run the pedals in reverse to move the chain it holds itself okay (the reverse of the way I have the bottom orientated in my photos! :-)
