If you’re looking for a unique gift idea for someone who enjoys putting models together, these models from UGEARS look fantastic. Designed in the Ukraine, these models are made of wood and have complex mechanisms with moving parts. The best part is that you don’t require batteries and you don’t need glue to put them together. Special tools are also not an requirement, although an Xacto knife is recommended for any trimming that you might need to do to the plywood parts. The model you see pictured above is a 3D puzzle safe that has a real combination lock on the front. The Safe model has 179 individual parts. UGEARS also offers several other models including a timer and a locomotive that has over 400 parts. I think these models would be a great project for a rainy day or no TV night. Prices start at $15.50. For more info visit UGEARS and Amazon.
