Features:

Two levers to precisely maneuver the arm

360° rotating base for full mobility

Stabilizers at the bottom for improved stability during operation

Rear compartment for storing small items

Smooth moving mechanisms designed with optimized tolerances

And most importantly… wheels!

The crane is easy to operate — simply use the levers to control the arm and explore its full range of motion. No engineering knowledge required, just start playing and experimenting.

After printing, rotate the base 180° so the crane is properly centered and the stabilizers are positioned at the front.

Printing is a bit challenging and requires a well-calibrated printer to achieve the best results. Tolerances for this model are set to 0.35 mm, with larger clearances at the base of the parts to help facilitate printing. It is essential to have the first layer properly tuned and retraction settings well configured so that all moving parts rotate smoothly. The model also includes bridges up to 16 mm.
