All can be printed with FDM. It really a shame that the funnels doesn't come with any type of effects so I made some lighting and flying effects for the Nu Ver Ka funnels.

Fin Funnels:
A remote weapon unique to the ν Gundam, model number: AEV/PFF93AR. When attacking, it bends into a U shape and a magnetic field is created between the two generator arms for generating and accelerating the mega particles. Despite their name, the fin funnels are in function "bits", since they have built-in generators rather than the E-caps used by funnels. While this made them more expensive to construct, it gives the fin funnels a longer operational time and allow them to fire more powerful beams compared to normal funnels. Each fin funnel has an output of 3.0 MW and can fire 7 shots in a single charge. The fin funnels also can generate a unique beam shield, known as a "fin funnel barrier", to protect against beam weaponry and solid projectiles. However, if an enemy funnel enters the barrier, it may cause physiological damage to the pilot due to psycho-wave interference. Although larger than normal funnels, the fin funnels have higher mobility as its triple block structure allows for AMBAC movements in addition to being propelled by its thruster. With the help of the Psycho-Frame technology, Amuro can control the fin funnels with his thoughts more effectively. ~Gundam Wiki
