Here is a general overview:

Model Details:

• Base Model: Dummy 13 (Original Creator) https://makerworld.com/en/models/183780?from=search#profileId-202639
• Head: Custom Model (@Maker81) https://www.printables.com/model/243642-lucky-13-ironman-head/files
• Chest and hands: Custom Model: (@Mici) https://makerworld.com/en/models/190609?from=search#profileId-242406

Edits:

Modified biceps, shoulders, internal bicep, and stomach to resemble Mk42 suit. Arms now look bigger as I extruded several angles, also added a bigger shoulder to give the model some more volume.

I included the stl files for reference. Edits were made in Fusion 360. 

Hands still need some work, as the top layer is too thin. If we get some traction with this model I could make time to work on the hands and some other ideas I have for the legs.

Note: With my setup I'm having a hard time to get the calves to print right so I print them separately in another bed with tree supports and brim, then I carefully remove these, I often break these when I'm not being careful. 

For the head, I printed supports for the inside part, and these were easily removed. I painted the head so I could multicolor print. 

The profile has 5 plates,

1. Print each plate with or without supports/brim according to the plate title.
2. Plate with the calves and mask ensure you use brim and tree supports and carefully remove these from the calves, the calves are a challenge but can be done carefully.
3. Follow Original Dummy 13 video for guidance on assembly.

Additional Notes:

• Post-Processing: After printing, I carefully removed the supports.

I'm printing in PLA however it is recommended to print in PETG 15 mm layer height infill 15%.

Enjoy,

I wanted to share some pictures of how it looks and compared to other figures I had for comparison. I also wanted to share that it printed and the settings I used to put it together and how it worked out, I did not edit anything on the models on this profile, my work was limited to sharing my profile and a brief guide to people who want to print it. Please consider this profile with this lense. I also want to thank the original creators and give them appropriate credit which is why I point you to those original models in this briefing.
