Iron Man MK42/43 Movable Jaw Concept


New Member
Hi all,

I am quite new here but just wanna share my current build and ideas on the movable jaw for the MK42/43 helmet.

I remembered seeing some posts regarding this but it somewhat died off...

Anyway, just want to share some details i noticed.


I was working on the helmet for easy 3Dprinting, I noticed that the inner cheek piece doesn't move when the jaw moves forward,.
Here's the result after some modifications to the helmet.

Here's a little link to the exploded view of the different parts for printing!

I'm still quite new to the simulation features in SW, so i guess I'm gonna just have it 3d printed and figure out the mechanisms.
Any suggestions for motorizing it...? (I'm a noob in these! =P)

Some progress on the 3D printed faceplate!
It's designed in 2 parts to save material on support and for my small printer!
Stuck together w acetone after tht.

Here's the progress of the print so far!
Everything seems to fit quite well tgther, though there's still some gaps here and there...

The jaw movements seems alright. Will post a vid on tht soon!

Gonna start figuring out the mechanism to motorized it! *fingers crossed*

I'm working on motorizing my mk42 as well, it's not like the mk3 where it has slots to put rods to the face plate can move up. The mk42/43 is gonna be a monster to tackle but xrobots on youtube has some good tutorials to watch for laying the groundwork to get started. I think just behind you in progress, I have to bondo, prime and paint it before I add electronics to it. I'm gonna have my tied into my forearm and arc reactor so it all works together. Good work though.

Thanks! I'll update my progress on the mechanism here!
It's definitely a challenge! But thts the fun of what we are doing isn't it! ^^

Been really busy with work and squeezing time for this!
Here's an update on my progress. Finally done finishing and painting!
Moving on to electronics and the mechanism now!
