3D tefillin model - for head (rosh) and arm (yad) created by user bcheirif which I've simply separated into individual models for convenience.
I've printed them washout any supports - the only place it would need support is where the straps go through, but its enough to let it bridge (at this size anyway).
They are quite small, but big enough for my 5 and 7 year olds to play with. I've put through some shoelaces (push them through with a toothpick). You really need pretty long shoelaces to have them hang over the shoulder and wrapped all the way around the arm for a proper tefillin look.
WARNING: be aware of what your kids doing with any kind of shoelace/rope. The head piece can fall on their neck and become a strangling hazard (lets say some other kid pulls him by it).
