FreeCAD Mini Digger

Version 0, started as a life-size sandbox prototype, finished as a toy

Considering the kids are ogres the goal was to make pieces easily replaceable 

For reference pictured model is about 130mm long

10 printed pieces total -- parts list below

Model shown is using various length 2.5mm bolts with nuts -- specifics below

Bolt size and other parameters can be changed in the file

Standard print settings at 0.3mm layer with exception of rod and rod rings at 0.2

Working on improvements: (a) prevent bucket jamming when overstretched (b) different base board options (c) double the size

Feedback welcome
