Spark plug USB flash drive(time lapse build)

Hello everyone
I wanted to share with you my recent project.
I have a small metalworking workshop and sometimes I like to play around with such pieces.
In the video, the entire process from beginning to end. I hope it will help those who want to do something similar.

Very nice indeed. You if have the time, or if you are in to that, maybe you could make a batch of pieces and commercialize them.

WD-40 the gift from the gods (rocket of course).
very nice work, how many hours in design stage and how many failed attempts?

Pretty neat!
