My son wanted to play with the big version of this. However, the version I printed while great was not very toddler proof so I reworked the model so that it would withstand his play.

If your child is even more exuberant with their play than mine, be sure to check out my remix where I switch the ball joints on the arms for cylindrical ones which is more closely linked to the branded brick version.

Changes
I arched the leg connections more to give a stronger grip - requires a little more push now but nothing crazy.
For the arm ball joints, I also arched them more to have a firmer grip and allows for more rough play while also allowing poses.

If you're looking for a 1:1 scaled version that works with branded bricks, be sure to check out my other version here:

Brick Skeleton Fixed Arms and No Gluing! 1:1 Scale

If you would prefer to have even stronger, fixed arms and with no gluing, be sure to check out my other version here:

Brick Skeleton Fixed Arms and No Gluing! 3:1 Scale

Be sure to use supports.
I have not tested it with Tree supports which should make it easier to remove but unsure on print quality.

I have used PLA but you can use others filaments to make this work.
