Monsters of the Mountain: Stalk-Eyed Rampager

Or just “Rampager” for short.

This creature was conceptualized by my son using Lego! He is very proud of his design and was thrilled to see it become an articulated printed toy as well.

Design Notes

Once again designed in FreeCAD v0.19 as time allowed over the course of a couple weeks. The legs and feet are by far my favorite part. I was aiming for something that looked agile and fast without being incredibly tall, and I think I nailed that goal and captured the essence of my son’s creation.

Parts List

15mm Wiggle/Googly Eyes (100% optional)

Helpful Tools

3D Printer capable of working with flexible materials

The 15mm Cute Eyes were made with a material change within Prusa Slicer, and I love these things so much I may go back and see how they look on the Dungeons & Derps figures designed last year.

2. Assemble Joints

Press-Fit AFJ-FreeCAD into all of the joint components as shown.

3. Assemble Limbs on Body

Press-fit the other end of the joints into SER-Body as shown.

4. Assemble Feet

Using a little super glue, fit SER-LeftFoot and SER-RightFoot into their respective legs as shown.

5. Assemble Eyes

Using a little super glue, fit and secure SER-EyePin into each of the eye stalks as well as SER-LeftEyeSocket and SER-RightEyeSocket.

Using a little more glue, fit and secure the 15mm Cute Eyes the way you want.

Alternatively, you can use SER-OptionalShorterEyePin and a 15mm Wiggle/Googly Eye, but I’m pretty much all-in on these cute eyes my daughter drew up. Using Wiggle/Googly Eyes will likely still be an option for future models, but I’m not going to highlight them anymore.

6. Rampage!

At least, as much as you feel necessary. The way my kids play with these creatures, they seem pretty tame and quite loving when interacting with each other. However, according to my son, they can shoot acid out of their “ant butt,” and they’re not above eating literally everything with the mouths on the insides of their eye stalks.
