I just built the device and it counts perfectly. But I can't work out how to quickly reset it to 000. Is there a way to do so without pulling it apart or pressing the actuator 1,000 times in total from the last time it was at 000?

What are the final dimensions (put together)?

150mm long x 100 mm wide x 115mm high

You could edit the digits so that it will count backwards (will then always count backwards)

0 -> 9 (this way, the counter starts at 999)
1 -> 8
2 -> 7
3 -> 6
4 -> 5
5 -> 4
6 -> 3
7 -> 2
8 -> 1
9 -> 0 (this way, it should change from 990 to 989 as it did from 009 to 010)

Do not think so without a quite major redesign.

Hey just wondering if the steel rod is 2mm or 0.2 mm

And how easy is it to push the button e.g could a rubber band hold the button easily or would it have to be quite taught?

A rubber band would work fine.

Could you post the step files for this model please, I have some findings that may improve this design.
