that might well be the shape of the gears. Did you just trace something or did you use a formula derived curve? Getting there though aren't you!! Cheers Ian

The gears are drawn using the proper geometry, in this case to MOD 0.5 dimensions. However, the printer prints somewhere between 0.05 and 0.15mm outside of the bounding box of the shape it's given, which is enough at this size to make a difference to the operation. I've tried to compensate for this by skimming 0.075mm off the edges in the model, and it works a lot better than the first ones I tried without the compensation.

Keep at it! You are getting some brilliant results! And this is a great blog, keep that going too! Cheers
