Miniature Diesel Generator box

Miniature Diesel Generator box with a lid. Would'nt even know it is a box.15 by 8 by 8cm. Designed to not need glue is a really snug fit. BUILDING:Have the 2 long sides and the floor part connected and flat to the ground upstright (Stable). Slide one of the smaller sides on (Be careful). It will be able to slide down but some force will be required. You don't want one side going in more then the other as it could snap the floor plugs (Thats why you want it flat on the ground). Once the first side is on the other side will slide in easily. Easy to print could be printed in stages with changing filiament if wanted. Would have to add pauses in print profile to achive this.
