Farm jack

It's taken a few attempts to get the model right but finally I have finished a tiny 1:32nd scale farm jack for the back of Andy's landy.

I was surprised that I could get as much detail as I have especially as the whole thing is only 60mm tall and 6mm at its widest. Only one side is any good but the other will be up against the back of the Defender 90 so it can hardly be seen.

I've had to use a trick I've worked out to stop the fine detail becoming a gooey mess.  I've included a superfluous support that is a fraction higher than the tallest part of the model.

Without it the final details are all printed in one go and the plastic never has time to set. The support forces the hot print head to move away long enough for the detail to cool down.

It's hard to see in the photo (click on it to get a larger picture) but the white one on the left is a mess while the silver one on the right has finished correctly just because of that extra rectangle.

I've used this trick on several model now.

I don't have a trick for getting all the tiny holes up the pole to print. I kept having to enlarge them and the pole until they formed at all! About 0.8mm diameter is the smallest hole that did not close up during printing.

The reverse side was a bit fiddly to clean up. I used a Dremel rotary tool with a grind stone bit and needle files. There is no detail on the reverse but it won't be seen.

The handle of the jack is made from 1mm diameter brass rod.
