Stone Age - Mecha T-Rex - Teratsoidot

Disclaimer: If I see any model I newly upload appear on Xianyu or other platforms, I may stop uploading permanently. For every instance I find, I will expose them here, and you can all go scold them.

I'll start by exposing one individual. Previously, three or four others also listed my Mecha Tyrannosaurus model for sale on other platforms, but after I commented, they all removed the listings and stopped selling. This particular person, however, didn't even bother to remove the term 'Mecha Tyrannosaurus' (I even tacitly allowed you to sell my Tyrannosaurus-humanoid dragons), and then blocked me. So, I'll be petty this one time and call him out here, helping him gain some traffic.

Everyone, please remember to boost first before printing; this can increase the success rate.

I can't believe it's been so long since my last model release. Seeing my models being sold without my permission truly makes me both angry and sad. That's why, even though I've created many models, I haven't published them. I also lament that in this era of 3D printing, with just a blueprint, it's incredibly easy to replicate something, requiring almost no time or cost. As a result, many people, for their own gain, violate agreements and erode trust. I condemn these individuals here.

Model Update Log:

2026/2/23: Uploaded the complete back model for character riding compatibility. In your existing character model files, import the complete back model, then combine it with your character model and adjust the position. Afterward, change the back part into a negative part to complete the character riding match.

2026/2/1: Uploaded model.

Model Printing Notes:

Size Adjustment: Due to the complex surface details of the Mecha Tyrannosaurus, to facilitate printing and increase the success rate, its size has been adjusted to be 30% larger than the original Tyrannosaurus. If you need it to be the same size as the original, simply scale all parts proportionally to 77%. I have successfully printed a smaller version (using 0.12mm layer height), but the results were average, so please consider this yourself.

A word on nostalgia: The Stone Age - Mecha Tyrannosaurus - Tera Soido, the reborn ultimate boss found only on floor 20F of the Dark Cave, is a pet almost every Stone Age player aspired to obtain. If I recall correctly, a character could only get one during the 5th rebirth, thus requiring multiple accounts, more top-ups, and more AFK farming, all just to acquire a high-growth Mecha Tyrannosaurus.

The overall structure of this model is identical to the Red Tyrannosaurus. Those printing the Mecha Tyrannosaurus here have likely printed the Red Tyrannosaurus before, so you can simply follow its assembly instructions; I won't elaborate further. For those who haven't printed the Red Tyrannosaurus, I recommend printing it first for practice before assembling the Mecha Tyrannosaurus, otherwise accidentally getting glue on the surface can be quite frustrating. Since silk filament is used, its layer adhesion is significantly different from regular filament. Therefore, you must be extra careful when removing supports in two specific areas, or the model might break: the back of the knee and the tip of the jaw.

The holes on the feet and base are designed for installing 8mm x 1-2mm magnets (mine are actually 1.8mm).

The print profile does not include support material, but using supports will certainly yield better results. Considering that users who opt for supports are likely not beginners and everyone's settings preferences vary, please download and adjust them yourself. Having H2C or U1 will be quite advantageous in this situation.

After reading the above description, you should understand that this is a time-consuming and high-risk project. Please consider carefully before printing; proceed at your own risk.

Finally, thank you for reading this far. I've shared my heartfelt thoughts with you all. Go ahead and print it now, and don't forget to boost and support. I also wish everyone a Happy New Year, full of 'Mecha' opportunities, and may you quickly become 'Tyrannosaurus'-rich.
