Created by agepbiz on Thingiverse, these are really cool little surprise eggs that come in four flavors. Dump Truck, Fork Lift, Backhoe and Front Loader (I’m sure he will design more). Easy to print and trust me when I say my grand kids love them. Reminds me of the Micro Machines of the early 90’s except for the egg of course. Very well designed and really fun to print.
