Information for size of air vent holes for the new enclosures of my Ts

[Ragnoso]

Merry Christmas to everyone, before I wanted to say that my Pterinochilus murinus RCF is fine. However since the substrate was too dump I decided to rehouse it and my other sling (Cyriopagopus lividus) in a bigger container of size 3.5"x2.3"x2.3". I made holes with 0.12" of size, but are they big enough for an escape for two 0.4" slings? (they have similar sizes). This is one of the boxes I drilled

The vent holes need to be smaller than the carapace of the spider to prevent escapes. Hard for me to judge without seeing the size of the spiders.

Measure them as the above poster said

Yeah you are just going to have to make double, extra, triple sure the above or they will escape!

Got lucky and took a shot of the C. lividus (seems to have a 0.2" carapace) meanwhile the P. murinus has a 0.12" carapace but the Pic I took is bad. I re-did the holes and now they are 0.04" wide
