Euro pallet, drawn in Fusion 360 after a blueprint.
I haven't printed this one (yet), I did the model to match my pallet frame:

Drawn in scale 1:1, so it needs to be scaled down in order to print. Top side down would probably be best when printing.
Fusion 360 file provided. All parts in the Fusion-model has separate bodies, in case someone wants to printed a broken pallet. :)
The author marked this model as their own original creation.
