(UPDATE) Gummy Bear Mech (Economy Version)

Disclaimer: This is NOT a remix of Gummy Bear Mech. GBM was only the inspiration.

UPDATE 05/11/2026: 

Added heavy variant.

I dig small mechs, especially mini ones like M13 THOR or the most recent release, Gummy Bear Mech. The problem is, I'm broke and don't have enough money for those. So I spent 3 hours figuring out how to make my own version. 

(I also found it resembles a caged-off CORE One [or C1+, or C1+ Gen 2] with robotic attachments.)

Below is a scaling list slightly edited from M13 THOR's description.

At 100%, you can quite comfortably fit a gummy bear in the cockpit.

At 270%, you can use a [POPULAR PLASTIC BUILDING BLOCK] minifigure.

At 400%, a Mini 13 will fit in the cockpit.

At 600%, a Dummy 13, Lucky 13, or Carbon 13 Type F will fit.

At 630%, a Carbon 13 Type M will fit.

Note: Excluding 100%, these stats are untested, they might be a bit large. I recommend previewing the scaling before printing.

If you don't want to use a real gummy bear, I provided a printable one slightly scaled down from this model.

Print Settings:

Print 2 cannons, 2 boots, 1 cockpit, 1 window, 1 plastic bear (optional) or gummy bear, and 8 clavicle joints (Default) and/or 2 cannon variants, the arms and legs + their ball pins from this model, 1 heavy body, 2 boots/original feet and 1 heavy armor (Heavy).

Layer height: 0.2 or lower

Infill: Doesn't matter

Supports: Only for "heavybearmech_body.stl".

Material: Any

Assembly (Default)

1. Get all your parts.

2. Connect 3 clavicles on each side.

3. Connect 1 clavicle on each ball at the back.

4. Connect the boots to the ends of the 3 clavicles.

5. Connect the cannons to the back clavicles.

6. Place the pilot bear inside the cockpit.

7. Attach the window (it may be a little loose since I added some compensation, what I like to call Bridge Hang Compensation).

8. Done!

Assembly (Heavy)

1. Get all your parts.

2. See this link for arm and leg assembly.

3. Attach the arms to the balls on the sides.

4. Attach the legs on the hip as shown in the original model.

5. Attach the boots from the default (or the feet from the figure).

6. Attach the heavy cannons to the top balls.

7. Place the bear inside the body and attach the armor (it's a little tighter than the window).

8. Done!

Additional Notes:

The size of the ball and socket joints are fully compatible with soozafone's other models, like Dummy 13 and Grabby the Claw. So mix 'n' match, and make whatever you want.

Any feedback would be greatly appreciated.
