Servo Hinge for Iron Man Helmet

thingiverse

This is a servo hinge setup for use with MIPRESIDENT's Iron Man Mark III helmet. You can see my final build here: http://www.thingiverse.com/make:286759. And a video of it in use here: https://youtu.be/q4N2HxEN5ng. You can follow me as I print and build the full suit on my channel here: https://youtu.be/aBibldoc0sg. This hinge setup requires no modification of the existing model and doesn't involve drilling/screwing through the sides. You will need to print: 1x Face Mount 1x Flat Top 1x Hinge Arm 1x Hinge Brackets 1x Second Hinge 1x Second Hinge Mount 1x Servo Mounts 2x Small Arms 1/2x Hinge Limiter (Optional) 1x Small Arm V2 (Optional) For this you will also require: 1x MG995 servo 1x servo micro controller (eg. Arduino Nano) 11x M4x10 Bolts 7/14 M4 Washers Extreme hold adhesive (Loctite 401 is an ideal adhesive for plastic to plastic, including PLA) I hope you enjoy printing and using my design.

Thank you!

Post-Printing Fit Top Block and Servo Mount Screw Servo into the two servo mount blocks as pictured (ensuring you get these the right way around), then use your adhesive to fix in the correct place (as pictured) on the flat side of the 'FlatTop' part. Do not glue the servo itself! This part has been designed to perfectly fit over the curved ridge inside the top of the helmet to provide a flat surface for the servo to sit on. Fitting Hinges Once your hinge mounts are dried, you can then attach the 'HingeArm' part to the servo and using one of the bolts and the washers, the 'FaceMount' piece to the other end. Once that is successfully fitted, you can then fit the 'SecondHinge' to the other side of the FaceMount in the same manner. Fitting Flat Top You can now fit this to the inside of your helmet. Gently, move the hinge arms until the Face Mount is flush against the inside of the mask front. Fitting Side Hinges In addition to your servo controlled arms, there are also two small slave hinges which help keep the mask pulled in the right angle. Each of these small arms are screwed into two of the 4 HingeBrackets, again, using a screw and one or two washers. Hinge Limiter Your helmet should now be ready to run. Once you are happy with your coding and motion, you may find that the short hinges move too far when the mask moves up and prevents it moving down again. If you are finding this is an issue, print out the 'Hinge Limiter'. HELP! I've fitted my small hinges incorrectly! Fear not, there may still be a solution. If your small hinges seem to restrict your helmet from opening, try printing out one of the "ShortArmV2" hinges. Replace one or both of your small arms with this and this should allow your helmet to open and close (I personally ended up having to use this on one side of my helmet).
