Transformers G1 Optimus Prime Scanned and 3D Printed Smokestack Set of 2 Silver PLA Optimus Prime is not included, neither is the chrome smokestack and these items are only for comparison so you can see exactly what you will get and the differences. Scanned on the Revopoint Mini 2 and printed with the Bambu Labs X1 Carbon. These are made from PLA, so take care as the tips are small and narrow and can break just like the original, so take care with them, don't try to test the strength or drop them as they will break. This is a 3D Printed Replacement set of smokestacks for G1 Optimus Prime or Ultra Magnus Smokestacks. The color is not a direct match. This is a stock image of one item, so there may be some very minor micro differences, but you will get one almost identical to this.
