Wind Tunnel

Hey everyone, I decided to take up a mini project of designing a small wind tunnel as my first 3D printing model upload! Note that this model should not be used to conduct any experiments as the design is not optimal in any way, and is intended for display purposes and showing the basic parts of a wind tunnel to curious individuals. Let me know your thoughts on any improvements I should make and happy printing!NB - I also included my attempt at a flow straightener.
