Racking tube dryer

Needed something to dry racking tubes after using them for my wine making. used different parts to come up with these two dryers. One is for a 40mm fan the other for 60mm fan. Each contains (1) 1/4 ID barb, (1) 5/16 ID barb, and (2) 3/8 ID barbs. The 40mm fan dried tubes overnight. I used ABS because I had it but it can be done with PLA
