Hello, Thanks for uploading this model.
I thought I'd try to print in ABS but am struggling with spiralvase given that it is only one later thick. Is it really printed with only one outer layer?
Is there a good reason why ABS is not used? Maybe that's my problem.
I am now attempting to print without spiral vase and thicker wall to see how it goes.
If this fails, I'm reverting to spiralvase PLA and will look at glues??? to strengthen the wall?
What glue did you use for the PLA boat you have?
