Ultimaker S5 - spool holder

I love the Ultimaker printer .. the S5 is my second one .. They made many good improvements with the S5. but really I do not understand why the kept the same Spool holder system as in the 3. Having the spool one behind the other is really not convenient
for me as I have some space limitation.

So I adapted some solution to have the 2 spools one over the other.

I hope you will find this useful as well
