Make sure you dial the infill up. I printed @ 15% and one of the frame bearing internal shafts broke off. I went for broke @100 but 50 should be enough. Thanks heaps to the designer.
I used 20% infill but I always use 4 shells for all of my prints. I prefer the added strength and water-tightness vs the extra plastic.
Thanks for the compliment! I'm glad you like the design! I like the orange btw!
