STL files should have the sizes. What are you opening them with?

Personally I use 3D-Tool's free viewer (second link down) which has a measuring abaility.

the man from the 3d chop say he cant find sizes?

Sorry, I misunderstood, you mean shop

Yes that one.

I expect he will require the scale at which you need them printing. From what I can make out from a quick measurement of the V3 top stl which shows the indent for the V3 EZ-B at 84 units, and the EZ-B V3 is 84mm long I guess scale should be 1:1

i wanted to let him print jd chest,but 1 cm weid each side..but female and chape from the ez-b4, keep desame.

i can see all sizes.i gave your link to the shop.so you helped hole belgium.and me.

thank you rich

STL files do not contain the units being used. Is that Maybe what they are asking for?

he cant import data from the stl in to the CAD program
