to put this together place the "blower spacer" on the inside of the "forge blower lid" and insert the pins into the holes. next set that piece aside and insert the small short stud of the "blower pin" into the small hole of the "forge blower impeller" and super glue it in. next set that aside and pick up the "blower handle" and super glue it to the small medium size stub that sticks off the very first piece you put together. you are now finished with the modification to make your forge blower run of you and not a motor. next place the modified impeller into the "forge blower case" and make sure the modified end is sticking out the lid. next fasten the lid to the rest of the blower however you desire. the final step is the take the "blower holder" and super glue it so the sphere on the end is sticking into the forge blower on the opposite side of the handle and holding the impeller from un-centering. you are now finished assembling you new forge blower and can go use it. just make sure you don't melt it.
note: i did not design the impeller, case, or lid. i only made the modifications.
print the blower pin and spacer at 100% and everything else at 20%. only use support for the pin.
