Tina Tries 3D Printing - Solving Scaling Issues with 325% More Mickey 🐭

In Episode 13 of Tina Tries, I 3D print and finish a giant Mickey Mouse (upscaled to 325%) — and show exactly how to fix the seams and gaps that appear on oversized 3D prints. Scaling up is trickier than it looks. Tiny seams at normal size turned into visible gaps once Mickey went giant. In this episode I walk through the problem spots, test two very different fixes, and share what actually saved time without ruining paint. You’ll learn: • When to use a 3D-printing pen vs. filler (strength, speed, sandability) • Filler primer + sanding workflow that hides layer lines • Paint choices for PLA that don’t stay tacky • Upscaling gotchas (splitting, alignment, cleanup) If you love Disney crafts, DIY decor, and 3D-printed props, this one’s for you! #DisneyDIY #MickeyMouse #3DPrinting #DIYDecor #Scaling3DPrints #SeamRepair #TinaTries ⸻ 🔗 Links & Credits Kos’ Page: https://makerworld.com/@gusDENTIST Model link: n/a ⸻ Want to print your own? 🛠️ Materials Used (Amazon Affiliate Links) • Creality Black PLA: https://amzn.to/4mWSHrl • Creality White PLA: https://amzn.to/46fwbCG • Overture Red PLA: https://amzn.to/4nR54VC • Overture Yellow PLA: https://amzn.to/3Wezfue • Mitreapel CA glue and spray: https://amzn.to/3KwPOio • Apple Barrel Matte Paint Starter Kit: https://amzn.to/47CCGSq • Rustoleum Rustic Pink Spray Paint: https://amzn.to/46VhxB8 • Plaid Wood Burning Tool: https://amzn.to/4gQoYxW • Plaid Wood Burning Accessory Kit: https://amzn.to/4npAtyN • MYNT3D Professional Printing Pen: https://amzn.to/3KvrJZp • DAP Plastic Wood Filler: https://amzn.to/4mKR8vs • 220 Grit Sandpaper: https://amzn.to/4pR6BNs • 400 Grit Sandpaper: https://amzn.to/3Ks9XGp • Gator 120 Grit Sandpaper: https://amzn.to/3KOoyvP ⸻ Recording your own build? 🎥Video Tech I’m Using (Amazon Affiliate Links) • MacBook Pro: https://amzn.to/4mlwane • iPad Pro: https://amzn.to/48OHyUW • DJI Microphone: https://amzn.to/3H9Quch • Light Kit: https://amzn.to/4nsCsSN ⸻ 🛍️ Want your own piece of Tina Tries history?
