Thumb Thumb from Spy Kids (second picture is a still from one of the movies)
I'm back at it with another cosplay project, this time it's a Thumb Thumb from the 2001 masterpiece Spy Kids (although they allegedly also appear in most of the sequels, which I haven't seen)
Because I'm obviously all thumbs, I made sure my 3D printer did most of the important work.
Materials:
- Close to 4kg of PLA filament (1kg in the helmet / head thing, 500g each for the hand things, and 1kg each for the foot things)
- Red shirt (off-the-shelf)
- Red sweatpants (off-the-shelf)
- Two red pillow covers and some safety pins to attack them to the sweatpants (I cut a hole in the top side while the bottom side falls over the foot covers)
- Heels to reduce my footprint area (second hand)
- Ribbons to enable my feet to lift up the foot pieces.
I used a Creative Commons thumb model as the basis for this costume. I had already measured my head with Cosplay Calipers and resized a base helmet design to fit my head using RefMaker, so I essentially just needed to adapt my base helmet to the thumb design.
I ended up printing the front and back parts of the head separate and made them attach and detach using magnets. I recently got my Creality Ender-6 working again, so the 57+ hour print of the front side was a good stress test. Didn't print anything on my Bambu Lab A1 Mini printer this time as the Ender-6's 250x250x400mm print area proved wonderful for my needs. For previous projects, I cut my models into way more parts which made them look less than ideal in the end. Eye holes are made by removing a cylinder (scaled along the X-axis) from the front side, then glueing in a part based on the same cylinder that has square holes made into it. I ended up scaling the eye lattice to be 1mm less wide than the hole for easier fitting.
The hand pieces are almost identical to the head piece, just uniformly scaled where the head uses about a 1.5x relative scale along the y-axis. I added a cylindrical hole for my hands to go in, and cylindrical grips inside those. The hands were printed upside down so I would essentially only need support material below the grips.
For the feet, I once again had to scale the model along the Y-axis. I removed a rectangular prism with rounded corners for my feet to go through and pretty much maxed out my Ender-6's print area (X and Z axes were exact fits to my printing area, I had a little bit of leeway along the Y axis and would have liked even more spare area but I couldn't reduce my footprint more along that axis than I was already doing with the heels). The end result has some truly off proportions along that axis.
I used ribbons I had once bought for a different cosplay project but didn't end up using to create bands that rest on my feet so I can actually walk with the thumb feet (without them my feet would simply go up through the 40cm tall hole, a recipe for disaster). These were glued to the inside of the foot tunnel with contact glue, whereas the front and back sides of the feet were attached to each other with cyanoacrylate glue.
To hide the horizontal platform on top of the thumb feet, I added pillow covers with holes in them for my legs that just about extend over the thumb feet's upper side. I affixed them to the sweatpants with safety pins. It gives the costume an unintended 70s disco vibe, resembling the flared pants of the era, and while it wasn't planned, I love it a lot.
