We didn’t design this model. It’s a community file from its original creator, and now and then a file has a fault that only shows up when we print it, such as walls that are too thin or parts that don’t join properly. If that happens we’ll let you know and try to fix the file, which can add a day or two. If we can’t get a good print from it, we’ll refund you in full.

Good to know before you order

TPU has a £11.50 print-order minimum. ABS, ASA, PC, Nylon and PETG-CF have a £46 minimum; PA-CF has a £69 minimum. Delivery is shown separately in your cart.

Please check the model files include everything you need before ordering. We print the files as published by the creator, so you receive the parts in the model, not necessarily a finished assembly shown in any photos. These are community designs by their original creators; we manufacture and post them but cannot guarantee fitment for your specific appliance or use case - check the original design page for compatibility.

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.

Original maker's notes

Original is Volvo ec210

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 2,5ÃÂÃÂ¢ÃÂ¢ÃÂÃÂÃÂÃÂ¬.
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.
