About this 3D model

This is a printable export of my Burr Puzzle design I've made for the MakeAnything competition! I can't afford a 3d printer, so the pictures are the puzzle made out of wood, NOT plastic. I've added bevels, and offset the pieces. However every printer is different, and I recomend testing two pieces and adjust the offsets as nessesary to see how well they fit. My design is shown here: http://www.puzzlewillbeplayed.com/666/Recede/ If I win the competition I will be able to make and test more puzzles like this. Feel free to messege me for the solution. There are only 7 pieces, but the assembly may still be difficult. Thank you for the chance
