This is a remix of https://www.thingiverse.com/thing:2865383. I've made following changes:

• Made the walls thinner, to reduce print time
• Added more tube entries
• Tube entries resized to fit tubes with a outer diameter of 16mm
• Added two water chambers on each side: Fill it with cotton and make it moist. But be careful!
• Added a simple holder (based on the original table holder)

Note: My printer did some weird stuff mid print, that's why my print looks so bad ;) i sealed the gaps with glue from the outside
