This diffuser is about the same length as the stock diffuser, but it comes up from the chassis about 4mm less than stock. This means you don't have to cut your bumper quite as much to run a chassis mounted diffuser. 

Can be printed at either 0.4/0.6 line width. No support necessary.

There are 3 versions:

• M3 through - if you want to use M3 nylocks
• M3 self tap - if you want to have the screw make its own thread. Minimum screw length of 8mm recommended for this
• Threaded insert - replaces the screw holes with two 4.1mm holes for M3 heat-stake inserts.
