HeavyDuty Spool Holder

i just wanted to design my own. printed a short and a long in pic and use a 6 inch bolt. no need to mirroring them and can be glued for better support.

8 - 608 skate bearing
4 - 5/16 inch at 6 inches long
4 - locking nylon nuts optional


i was going by the size of Sulotech's spool size.
