Achtung, alle Einheiten! A new unit has entered the field!

Introducing the Wiesel Mk20 and 1A4 the smallest armored vehicle's in service with the German Bundeswehr! Originally developed to replace the Kraka for airborne operations, the Wiesel is a lightweight, air-transportable weapon carrier now available in 1/16 scale!

This detailed model features:

• Realistic, fully functional tracks
• Working lights
• Gun rotation of 90 degrees to each side
• Elevation and depression for the main gun

This model is something I’ve wanted to build for ages, and now, thanks to the new Cyberbrick system, it’s finally possible. Since I operate a small 1/16 scale RC tank fleet, the Wiesel was a must-build right from the start.

This is also the first RC vehicle I’ve ever built. Up until now, I mostly worked at a print farm designing lighting solutions and creating H0-scale wagons. That means there will definitely be updates and improvements as the Wiesel goes through its service life. 

Current Main Roadmap

✅ Create working headlights (Completed)

✅ Better Tracks (Completed)
✅ Wiesel 1A4 variant (Completed)
✅ Wiesel 1A1 TOW variant (Completed)

IMPORTANT NOTES:

• This model is designed with the mindset of a scale model, not a toy. It contains small and fragile parts that may break if mishandled.
• Don’t change the layer height settings! For items like the gun for example, using a lower layer height might seem like it would improve the appearance, but in reality, it often makes the final print worse.
• Please note: Track printing may fail unless the correct filament settings are used. (Tests were conducted on a Bambu Lab Plei plate. Results may vary with other plates.)
   Be sure to:
     o    Use a layerheight of 0.1 as the objects standard.
     o    Set the initial layer speed to 25 mm/s.
     o    Set the initial layer infill to 50 mm/s.
     o    Use Bambu Lab Charcoal Black PLA Matte. (Tolerances may vary for other materials.)

• The “non-manifold edges” warning is a false alarm caused by using CAD files for 3D printing. This does not affect printability or functionality of the model. Running a repair may actually break things, such as dimensional accuracy and multi-color support. It is safe to proceed without repairing.
   

  

Want to print it as a display model? Or have you already built it but need the motors for a different project? Check out our Dummy N20 Print-in-Place with Rotatable Axle: https://makerworld.com/en/models/1703825-dummy-n20-print-in-place-with-rotatable-axle#profileId-1807092

Please note:
It appears that Bambu Lab units now come with 50 mm cables instead of 100 mm on the motors. These shorter cables may not reach their connection points. To address this, our bill of materials now includes loose 100 mm cables for anyone who needs them.
