Frequently Asked Questions

Q: Is your model radio controlled (RC)?

A: Yes, our models can be fully radio controlled and has controlled forward/reverse control and steering, you can use any RC transmitter/receiver.

Q: What do I need to build your model?

A: You will need just the following:

  • 3D printer (reqs. listed above)
  • Printing Filament (PLA or PET, 2 kg of black colour, 0.75 kg of other colour)
  • Fasteners (full list in Build Guide on page 5)
  • RC equipment (transmitter, receiver, motor and controller, steering servo, battery)
  • Set of Tires
  • Set of springs with shock absorbers
Q: Which 3D printer models are compatible with 3dsets products?

A: Virtually any FDM-based printer! We recommend to use the Prusa MK2/3 3D printers, however our kits are designed for all common "FDM" printers, which use plastic fillaments as the printing material. Minimum required print area dimensions are 200 x 200 x 180 mm. You can print on “delta” printers too, you will need cylindrical print area at least 230 x 180 mm.

Q: Are the separate parts available in .stl file format?

A: Sure! Next to the predefined printing bed sets, you will get all individual parts in .stl format, so you can manage printing as you wish.

Q: What is the recommended printing setup?

A: There is nothing special, we use the following settings:

  • for Body parts: Infill 20%
  • for Gears, Shafts, Axles, Arms: Infill 100%
  • for Seats: infill 10%
  • recommended layer height: 0.10 - 0.2 mm
  • printer nozzle: standard 0.4 mm
Q: What kind of filament do you reccomend for printing?

A: We recommend PLA or PET filaments. We have the best experience with Fillamentum PLA premium printing materials.

Q: Is it necessary to generate print support for some parts?

A: Absolutely no! Parts that need printing supports have supports made by us already. These parts/supports are verified so you don't have to worry about supports.

Q: I have a printer with a print area of 150 x 150 x 150 mm. Can I distribute the parts into multiple prints and print the whole model this way?

A: Unfortunately, some parts are too large and require a bed size of 200 x 200 mm so they cannot be printed on smaller beds.

Q: I can not insert a bearing into its place.

A: For the smallest operational clearances, only minimum enlargement of the holes is set. If you are not able to calibrate your 3D printer properly, try to carefully grind the parts or use the hammer when inserting the bearing on its place. When using a hammer always keep caution!

Q: I have some "bearings xxxx”. Can I use them in your model?

A: To construct the model are needed any bearings having these parameters:

  • outer diameter 15 mm
  • inner diameter 10 mm
  • bearing width 5 mm.

They are commonly sold as “6700ZZ bearing” and you will need a total of 28 pieces.


Q: Do I have to buy tires? I cannot 3D print them?

A: In this specific case, we recommend buying tires because their characteristics are be significantly better than 3D printed tires and the price of the purchased tires is comparable or cheaper than the price for the flexible filament consumed to print them.

Q: Some parts do not hold on my printing pad, what can I do with it?

A: At first, please try to clean the print pad properly. If you use Prusa MK2/2.5/3, use the IPA (isopropylalcohol) for cleaning. If specific part still does not adhere on the pad, then use the file for the Prusa Slicer with saved parts, delete the specific part and prinit it separately with the “brim” setting activated.
