3D Printed wind up car

This working prototype is the result of lots of hard work, a few print iterations, a TON of design iterations and a bit of dumb luck (in the form of a few lucky guesses) 
Link to Car
I was very excited pulling this little toy car out of the box when it finally arrived and have been quite surprised by its performance after only a few actual prints of the whole wind-up gear box system! (I was surprised it moved at all)

At this point in time the car only moves about 50cm once fully wound up but i hope to increase this distance in the future!

This Wind-up toy car is printed in one piece by using Shapeways SLS nylon printer and comes with it's own key.
It can be wound up with the key, or by simply pulling the car back.

The wind up car at the moment is available in Beta as i'm trying to work out a few kinks
(the main one being the fact that the car required quite a bit of manual cleaning to get the parts moving)

Through the Beta processes i'm looking for any suggestions to improve this design! 
(I have already uploaded an update that improves some aspects)

3D Printed Jewelry

These are my very first designs! 

All of my items use 3D printing techniques in some way to achieve the final design. 

The designs usually start out as a rough hand sketch before I use 3D modeling software, which is used to create the final design. 
The designs are then sent to be created, we use the 3D printing company "Shapeways" to help manufacture all of our iteams. All nylon plastic products are directly printed using the Selective laser sintering method. All steel products are also directly printed first, before being metal plated if necessary. All items to be made in precious and semi-precious metals are first 3D printed in wax. The wax model is then used to create a plaster cast which is then used to cast the metals. 

All these items can be ordered through our Shapeways store.
