Print blocks?

Garage sale finds today.

The only one that concerns me is the battery. If printed the word battery would be reversed.

Hadn't noticed that. Wierd.

Nice finds 63cagedfalcon. I agree with firemanphob - "batteries" would be mirrored if it was a normal block.

They don't look like they're mounted on wood. They could be from some kind of child's play set. Perhaps Playdough?

I dont think printing blocks have all the little holes.... pretty neat though

Cool find, congrats!

From same group just no cool factor.
Not revered either.

I've got it.....sand casting mold.

Press this into sand, holes let air out.
Remove rubber mold, pour molten aluminum & bam, exact copy.

Still not sure about thin aluminum excavator or welder blocks but lathe, chainsaw & saddle are completed examples

I think you got it, might have bin from a school metal shop..... The motorcycle looks to be a 3 cylinder 2 stroke liquid cooled Suzuki 750 water buffalo
