A capsule to house crickets to make them easier to dust with calcium to feed your pet lizard.Please print the objects in the orientation that they appear in the original files. They are labeled cbottom, cmiddle, ctop, and cdoor. cmiddle takes the longest to print. Everything fits together and can be placed nicely into the corner of your lizards terrarium. The crickets can be dusted and housed in the printed rock shape and then can be released through the use of the door. This object is currently being used in my friend's terrarium and has served him well thus far!
