This Episodes Question:

Hi all,  I have recently build my first voron . Hell yeah .It's a 2.4 Ldo motors edition. But now Iam ready with that i where thinking aboud thé next step . I'am thinking aboud a mmu system for it . I have seen thé trad rack and thé box turtle . But i heard the box turtle is more popular than thé trad rack . Co pilot gives me thé intention thé trad rack is cheaper but has also a bit more faults in it than thé box turtle . I love to build things so buying a of the shelf mmu system is not a option. Could you guy's talk aboud what are your pro's and neg's aboud these systems what you have build and which one you Prefer and why ?  I'am now more pulling towards thé trad rack because of the possibility of more fillements and i thinks it looks cooler  You guy's would help me with this so i can decide better  Kind regards Jeroen from Belgium
