Fillament Spool Top-strengthened

The original part is pretty neat, but too fragile. The upper part snapped off the second time I spun it up :-( I didn't want to play with the scaling to get an exact fit or play with glue either. I added the threaded holes and made its solid. I'm planning on printing it with 20% infill. I haven't printed it yet, but will be tonight. Hopefully I got the scaling on the threaded connecting rod right...

Update- I uploaded a new scaled threaded rod today 9/19/17. This one works as do the other two parts, pictures were added as well... Have fun.
