Brick Megafigure (10:1 scale)

This is a big toy human figure . I spent a lot of time making this model from scratch to match the original design while making tweaks for tolerances, printability, and strength. While there were a number of brick figure models I found online, most were not designed for printing, which is a particular challenge for the leg, arm, and hand joints. I'm particularly proud of the universal clip I designed for these, which makes for easy assembly and stiff-enough joints to pose your figure.

I designed the clips and tolerances for this model to be printed at 100% (10x original toy building brick scale), but people have previously had success printing my 10x Brick skeleton at smaller scales (eg, 50% or 5x scale).

Now that I have a base model for a Lego-like figure, this opens up a host of options for specific Lego-like figures. If there's something particular you're interested in, leave a comment or send me a message! If you want to make your own modifications, I've included STEP files for all parts (just be sure to give credit for my original design).

Fully assembled, this model stands 40 cm (~16 inches) tall. I printed mine with Hatchbox true blue PLA, Hatchbox true red PLA, and Prusament mango yellow PETG.

Printing Instructions

I've included 3MF files for all parts, and parts should import correctly oriented for printing.

• For PrusaSlicer 2.6+: you just need to load the project file. (This makes use of organic supports, for the legs, which are added with PrusaSlicer 2.6.)
• For other slicers: I've included details about special instructions for all parts, so you should be able to replicate anything necessary for proper printing. Except where otherwise noted, I printed parts in PLA at 0.15mm layer height with 7% cubic infill and without supports.

You will need to print:

• 32x-connector-pins.3mf: You should need 30 pins for assembly (or 26 if you print the solid head); this has 2 extra just in case. If you have trouble with bed adhesion, add a brim

Legs

• legs.3mf: Uses tree supports the top of the lower hole on the leg.
• hips.3mf
• 2x-limb-clips.3mf: This file contains two clips. You'll need to print one set of two in the arm/body color, and one set in the leg color. Important: I recommend printing this in PETG or ABS with 25% infill, because it will have to flex and PLA might snap.

Body

• arms.3mf: These print with a small surface area on the bed (the wrists), so you might want to add a brim if you have trouble with bed adhesion.
• body.3mf
• 2x-limb-clips.3mf: This file contains two clips. You'll need to print one set of two in the arm/body color, and one set in the leg color. Important: I recommend printing this in PETG or ABS with 25% infill, because it will have to flex and PLA might snap.

Head & hands

• 2x-hands-wrists.3mf: Requires supports on the underside of the wrist clip. Like the limb clips, I recommend printing with PETG (or similar) with 25% infill.
• One of: (all require supports on the underside curve of the head)
  • head-face-mmu.3mf: Print the head & face as one part with some sort of multi-material printer (e.g., Prusa MMU or Bambu AMS). Use supports on the underside curve of the head.
  • head-split.3mf and face.3mf: Print the head (with cutouts) in two pieces. Use pins and glue to connect the halves. Print the face separately and glue it in.
  • head-solid.3mf and face.3mf: Print the head and face as separate prints. Use supports on the underside curve of the head. Then glue the face parts into the head.
  • head-split-blank.3mf: Head in two pieces with no face cutouts
  • head-solid-blank.3mf: Single-piece head (with supports) with no face cutout

Assembly Instructions

In addition to the printed parts, you will need cyanoacrylate glue (CA glue/superglue). 

Legs

1. Glue the pins into the top of the hip. Add glue to the holes and bottom surface of each of the hip pegs and attach. Important: The slope of each hip peg should be facing out to the sides. If the pins don't want to go together, check that you have this orientation right!
2. Use the same gluing approach to attach the limb clips to each side of the hips.
3. Gently but firmly press each leg onto the clips. It should snap into place. The hips are symmetric, so you can't put the legs on backwards. This requires a fair bit of force, but you shouldn't need a hammer. If it won't go on, slightly sand or file down the outer head of the limb clip (rather than the inside of the hole on the leg). Warning: The clips are not designed to come out once they're attached, so make sure you're ready.

Body

1. Glue the limb clips into each arm, like you did for the legs.
2. Glue the wrist onto the hand, with the pins. Because of the relative print orientations here, it's best to use a bit more glue here to make sure it stays on.
3. Press each wrist clip into the arm. (They're the same, so you can't put in the wrong hand.)
4. Press each arm clip into the body. The body is also symmetric, so you can't put the arms on backwards.

Head

If you printed the separate head and face pieces, glue the face pieces into the head. You may need to file or sand some of the face pieces to fit, depending on how well the supports worked.
