First of all thank you for being interested on my design, here i will tell you some things to take into consideration for this print. 

1. As you migth know i used magnets for the suspension, so you have to print it with no supports and you have to stop the print in the slicer in some certain layers.  I cant tell you the exact layer cause it depends on the parameters that you are using.  If you dont know what im talking about, here's a video that explains how to do it :

       2. The magnets used are neodimium magnets 7x1,5mm. I reccomend doing this print very slow because the space for the magnets is tiny and the more slow you are, the better output you will achieve, but of course it depends on how do you set your printer.

Happy printing! if you dont understand some settings or something i will be glad to answer you!
