This came about during a live stream of Fun King 3D, the subject of Benchy's came up and everyone started mentioning the different iterations of Benchy's and I noticed I had never seen a Submarine Benchy!
Not wanting to just do a remix by taking the cabin and putting it on a submarine, took the original concept of the Benchy as an early cabin boat from the 30's or 40's (my interpretation) so I wanted an "older" style submarine, just a little cartoonish.
I designed this based on the one man subs the Japanese used during the Pearl Harbor attack, small and simple.
the two prints are at 50% and 75%, smaller than 50 and the bars on the windows wont print well.
(9-16-18)Slight update, may need a raft depending on printer. Mine printed fine on the CR-10S but the tailfin failed on my Prusa (Sorry Walter)
(9-18-18) Another update due to inconsistencies in printing on different machines. I added built in support for the horizontal fins and increased the length of the fins so the first layer prints as one piece so no brim will be needed. PLEASE NOTE THIS CAN BE A LONG PRINT IF DONE AT FULL SIZE, BEST SIZE IS 75%
Printed Solid "Daily" PLA
Orange, blue and red
Printed at 215 on a 60deg bed
Used Fusion 360 and started with a tube shape and just started adding to it until it "looked" right
