About this 3D model

It's an experimental little speaker with 3CM magnets (neodime is the must) .this speaker is full pla but the membrane is better in "canson" paper 120gr/m http://www.youtube.com/watch?v=pDdmziCc1wU&feature=youtu.be ATTENTION : glue and screw M3 two stl must be printed in pla flex : spider and surpresser and you must have special bobin copper ( 0,4mm recomended) (bas rendement) my speaker protype use 0,2mm coper , ferrite magnet and pla membrane for make realy better use neodyme magnet ,0,4mm copper and paper membrane it's realy printable but the pla flex is hard to impress have a good print
