3D Printing STEAM Enrichment for portland kids

3rd to 8th graders design, engineer, and bring their ideas to life through 3D printing with PDX MiniMakers: where science, technology, engineering, arts, and math aren't separate subjects, they're just Tuesday afternoon

“I used to dread Mondays because it meant the start of a new school week, but now I’m excited for them because of 3D printing!”

~ Maxwell, Student (Age 11)
Did You Know?
3D printers can make prosthetic hands for kids at a fraction of hospital costs. Student groups worldwide design and print these devices, showing how engineering skills can directly help others in their community.

About Us

Hello Portland Community!

We’re PDX MiniMakers, a hands-on after-school enrichment program where Portland 3rd-8th grade students explore engineering, design, and problem-solving through 3D printing.

We believe every child should have access to creative, cutting-edge learning and tools that fuel their future.

Planning for the Fall Quarter? Llewellyn and Creston Elementary parents can register now!

Alameda, Bridlemile, Capitol Hill (and more!) are being finalized - registration page coming soon!

At our 3D printing workshops, students will:

Learn how 3D printers, software, and tools work

Build creativity, pride, and self-confidence skills

Take home what they create (all materials included!)

Design, engineer, and print their own 3D models

Matthew Thogerson

Matt is a maker, tinkerer, and creative problem-solver with a deep enthusiasm for hands-on learning.
He first got into 3D printing while designing a tabletop war game, and quickly discovered how powerful digital fabrication can be as a learning tool. Today, he uses 3D printing for everything from tabletop gaming and costuming to practical problem-solving around the house.
Matt has a strong passion for working with kids and helping them build confidence through creativity. He believes the best learning happens when curiosity leads and mistakes are treated as part of the process. At PDX MiniMakers, he enjoys helping students turn ideas into physical objects while learning how tools, technology, and imagination intersect.
He’s excited to be part of a community that encourages experimentation, critical thinking, and joyful making.

Josh Dunne

Lifelong learner and tinkerer. Experienced mentor, educator, and creative problem solver.
Josh moved to Portland with his family in December 2019. His children have attended Abernethy, Hosford and Cleveland schools. Josh is also a volunteer for the Cleveland Weekend Warriors cleanup program. Prior to moving to Portland Josh was a Radiology PACS Administrator for UK Healthcare supporting highly complex diagnostic imaging applications and modalities. His background as a PACS Administrator was a perfect foundation for understanding 3D printing software and technologies. While in Kentucky Josh also enjoyed being an assistant coach with the elementary school cross country team.
Josh is a voracious learner and is constantly seeking out new technologies, modalities, mediums and workflows that he incorporates into a variety of hobbies. In his free time Josh loves to create custom DnD miniatures and is always working to improve his painting skills on them once complete. Josh also uses 3D printing technology to create a variety of different types of art, jewelry and other novelties that incorporate a range of mediums and workflows.

Josh is super excited about the opportunities that 3D printing provides young, inventive minds. He strives to provide a safe and collaborative environment that encourages fun and creative problem solving.

Weston Baker

Weston Baker is an engineer, fixer, and lifelong learner.
As a high school student, Weston volunteered for several weeks at a camp teaching sixth graders about nature and community. It was one of the more impactful experiences of his life and planted the seed for his continued interest in being an educator. He was first exposed to 3D printing while working towards his engineering degree and was impressed with the accessibility of this manufacturing process to the average person. He has created artistic projects, practical components for repairs, and professional prototypes for mechanical components using 3D printing technology.
Weston is inspired every class by the creativity that kids possess and their ability to quickly learn how to bring their ideas to life through new digital and physical tools. He looks forward to encouraging this learning process and witnessing the moments when each new concept clicks.
In addition to teaching, Weston enjoys reading at the library, watching behind-the-scenes documentaries, and going backpacking.
