As a special request to Eric. Please check the sizing as it was at best a guess for me.

Check the original and then resize where nedded. Find out the % you have adjusted and then apply that % to the pieces. Use windows 3D Builder to select all high light the one you want to save and then delete the rest. Rewind or reverse and then repeat until all individual files are saved ready to print. I've sliced it up, so that you should not need any support, although its up to you, Should print well. Good luck Cheers Jace
