I did some drawing and designing again for 3D printable parts.
Made some 3D printed concrete parts and clamps for lifting.
2 clamps for AAC blocks and some sets of blocks in different sizes.
And 1 clamp for mega blocks and 2 model blocks.
Can be used as load or for on a crane , loadercrane , shovel , etc.
They can de ordered at shapeways :
