Solidoodle Spool Holder by mk1 - inserts for larger spools

I love this design for the spool holder by mk1 but the holder does not fit the larger spools. I have designed an insert for the spools that lifts them up off the frame. This is more of an add on than a remake. This fits most of the filament spools we have gotten so far. inner hole fits the 1inch PVC pipe the holder is designed to use.
