UGEARSTheatre - 70 Parts - 3D Wooden Puzzle - Mechanical Model - Ugr-70002, 8.4 x 7.4 x 3 Inches Brown

Does this require any further materials such as glue etc., or is it ready to complete right out of the box?

Dimensions says 37.5 x 17 x 3 inches. but it doesnt appear 3ft large in review pics. can someone post the approx assembled size? thank you.

Is this something you can paint or stain?

Is anyone having a problem with the toothpicks being too short?
