I made this for my girlfriend based on this lipstick organizer : http://www.thingiverse.com/thing:334128
The size of the nail polish bottles is 29mm x 29mm then I made 30mm x 30mm size.
The holes are made to use less plastic.
In the version I printed (see picture), I forgot to put holes in the bottom of it, and it took approx. 4h in 0.4 resolution on my Freesculpt EX2.
Feel free to ask if there is anything with that model ;)
