Bit Adapter Box

Hello,
this is an box for my three Bits to Hex extension so they don't have to be in a bag anymore. Biggest adapter is 7,4 cm long.
I designed it with freecad and printed it with my Ender-3 V2. It doesn't need any helping structures but I used some for the cover. Both printed together needs ~ 4 hours.
Hope you can use it well.
