About this print
A toy excavator model intended for display or play. Excavators are digging machines used on construction sites, recognised by their articulated arm and digging bucket, and this model replicates that general form in printable parts. PLA is a reliable choice for toy components, printing cleanly at most settings and available in a wide range of colours to suit either a realistic or more colourful finish.

And yes: there is sand at the teeth of the bucket out of my kids sandbox ;-)
I hope the pictures are descibing the project best. On pic SAM_4173 the lower part of the body is shown with holes for batteries. It was redesigned that a big pb battery fits now. The two servos in the arm have about 120 Ncm, the big one in the body about 260 Ncm.
In the tracks and for turnig there are the the cheapest servos ever in there for about 2,5ÃÂââÃÂÃÂÃÂì.
The servos in the tracks are hacked so that the pwm signal still works but they do it continously. Just search the web for "pwm servo hack"!
In the turnshaft i soldered the + and - of the servos togeter to reduce lines from 6 to 4.
The tooth gears are bought:

Printing Excavator
For Excavator we would normally reach for PLA — it is easy to print, low-odour and plenty strong for everyday use. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
