Building off my caulk gun idea, I thought it might be useful to use liquids such as paint or acetone in a controlled manner. Enter the syringe pump. I found some files on thingiverse that got me started and allowed for a quick proof of concept. However, the design was both lacking and intended for a different motor, so it required lots of changes. you can see some of my process in these pictures. Maybe If the pump works and I clean up the file I’ll post a remake to thingiverse to keep the love going.
