I modified the top by adding text to celebrate my friend's brithday. Overall I thought it came out good, the body was super easy to print and well-designed. However, I ran into problems with the top(really cool design btw :)) I had to size the top to 104% size to make the threads fit snugly, anything less wouldn't work. Also, I personally had problems with supports on my printer, no fault of the design but, I wish the threads would have printed better without using supports, maybe do bigger threads. Overall, great design, and I'm sure my friend will love it.
