Funnel for refilling your gear oil on your Vespa (should fit for P series and T5 and may fit other models) or Genuine Stella (at least the 2t model). Nothing fancy.
It's slow to drain the thicker gear oil, but it sticks in the oil hole and stands up hands free (so i do this step while I'm cleaning up). You may have to sand or cut off a little bit of PLA slop at the point where it enters the hole- due to the angle of the spout, the makerbot isn't as clean with that portion (assuming that you grow it upside down without support).
Load to Makerbot. Cut or sand off about 1/2" or 1cm of PLA slop where the spout goes into the gear oil hole. Fill with oil and allow it to drain. Repeat until oil compartment is full.
