Multiple Spool Holder Expandable

-------------------------------------------The wood part is Ø21mm------------------------------------------

Thought I'd design something easy to print that holds my spools so I can access all of them without lifting every spool to access the one in the bottom. It takes about 2h per piece, printed laying down flat. How many spools you fit is up to you how long you make the wood part. Mine is around 70cm and fits 9-10 spools.
