Cable-CAM Crawler for NXT/EV3

A dedicated NXT/EV3 GoPro Cable Crawling Robot. You will need to purchase some cable wheels to complete the design (STLhive parts) – or use the ones you have already. Use big wheels for flat, taught cables and small wheels for slack lines (line must be as taught as possible. Lines may sag if very long).

This product in combination with your LEGO Mindstorms NXT/EV3 & GoPro can be used to time lapse or cool school shots for videos and yearbook.

This design is held together with No.8 Pan-head screws. The cable should be between 1/8″ and 1/4″ in diameter for best results. More products will become available to be used with this design as they are requested by customers.

STLhive 3D printing Product Feature/Benefits:

  • Rubber band line tensioners ensure the cable crawler has good grip (Rubber bands not shown).
  • Safety Hooks prevent the cable crawler from falling off of the line.
  • Designed to work with NXT and EV3 robot kits and GoPro Cameras.
  • Fully adjustable camera pivot (inline with cable).
  • Designed to be rugged and to utilise off-the-shelf parts.
  • We recommend using our Free GoPro knob to complete the design.
  • Print orientation (As shown) is intended to maximise part strength but may require more support material. Reorientation of the part may result in less required support material but may dangerously weaken the part resulting in the part breaking while in use.

Purchasing / Downloading:

  • You have 24 hours to download your parts after purchase.
  • When you buy this part, you get “.STL” files in a “Zipped” folder (For Windows).


  • STLhive’s recommended printing suggestions are determined based upon the part’s usage. Safety is out main concern.
  • Alternate orientations may provide prints that use less support material but you do so at your own risk. We try whenever possible to orient the grain structure to maximize part strength.
  • This part is intended to be printed using high quality printers; and is modeled with great attention to detail. Printing quality is determined by the printer you are using, your printer set-up and by the type and quality of material used.
  • Filament based printers (like Makerbot and RepRap) may struggle to provide a part that is easily freed from support material.
