There are 5 peices to this. The end piece, the frame, the middle peice, the small peg, and the large peg. If you are just trying to frame one hotwheel then you need to print 2 end peices and 4 small pegs. The small pegs connect the end peice and the larger peg with the middle peice connects two frame together. To put the hotwheel into the frame you slide it into the channel. If there is anything that could be done to make this better please let me know.
