Building a rack question

[ARBallMorphs]

hey everyone,

I got 2 racks at home that i build myself and they are functioning great.

Now i need to make a new rack with bigger tubs, i have watched some youtube clips on making your own rack and some racks have open sides while the racks i made are only open in the front.

This made me wonder is it no problem for your ball pythons the sides are open too? i was thinking that they may feel less secure?

I am asking this as making them with the open sides seems alot easier, faster and cheaper to do.

so any advice and idea's on the matter are welcome
