Okköbi Egg-Incubator OBI-12 - Roller

This Roller is for the Okköbi Egg-Incubator OBI-12. 

I made it because i wanted to hatch more Quail eggs with it. There are 5 Roller with the Incubator and you can add 2 more but i couldn't find it anywhere to buy so i tried modeling it.
Before i could hatch 16 Quail eggs, now i can hatch 24! :)

Hope this can be useful for someone else too. Enjoy!
