About this 3D model

Designed and modeled a case for my Mavic Pro propellors. I often travel with the propellors off the drone so they don't get damaged and was looking for a solution to carry them separately. These only carry 4 at a time but they are seated in the case so they are not damaged rattling against the case or each other. The fit is relatively tight, my printer is tuned so they fit snugly but your experience may vary. If you've got any comments or suggestions please put them below!
