Wood Trick Ölbohrturm Spielzeug - Mechanisches Modell für Ölpumpenheber - 3D-Holzpuzzle, Montagespielzeug - STEM-Spielzeug für Jungen und Mädchen

This takes some effort to build, it’s definitely for adults. You also use a lot of sharp toothpicks to keep the parts together (no glue!) and so you have to be very careful you don’t stab yourself trying to push toothpicks through the holes. Using needle nose pliers helps a lot to avoid injury.Also, you have to sand the gears and wax them well as you’re building to make sure everything functions. It’s very hard to reverse mistakes so go slow. Overall, it was well worth it and when I operate it its extremely cool!! This is very well made too, not a cheap Chinese product and the parts are laser cut. I was so impressed I bought another product from them.

It’s propelled by elastic, which means it does not go on for very long and moves very fast.Make sure to wax the pieces because initially, the pieces all got stuck and the model wouldn’t move, we had to take it apart to wax everything and put it back together again

War mein erstes 3D-Holzpuzzle.Am Anfang war ich ein wenig skeptisch...aber mit jedem weiteren Teil wuchs meine Begeisterung.Wird nicht mein Letztes sein

Je suis en train de réfléchir à remplacer le moteur à élastique par un petit moteur électrique.

Cuando lo monten en regalo Navidad
