Falk excavator arm holder hook replacement

This is a remix with some modifications as stated to make it easier to print and more sturdy.

For Falk / Falquet & Cie SAS made excavators arm that are available for mounting on toy tractors, but also tracked excavators.

Printed in Polymaker PLA with support, used high infill (most of the model is hollow, so only relevant parts get infilled).

• Fused the two halves back together as I had some issues with lifting on my printer otherwise. Needs to be printed with support.
• Made the bolt part stronger (filled) as I had issues with the bolts breaking off.
