Hi everyone, I'm a 14-year-old who enjoys designing and sharing 3D models on MakerWorld. I'm curious how many MakerWorld points (or gift card rewards) people typically need to earn before they can afford an H2D printer. If you've already bought an H2D using MakerWorld rewards, how many points did it take you, and how long did it take to earn them? I'm trying to set a long-term goal for myself and would love to hear about your experiences. Thanks!

I designed a simple optical illusion that looks like an uphill slope, but it's actually downhill. From certain viewing angles, your brain interprets the track incorrectly, creating the impression that gravity is working in reverse. No electronics, no tricks—just geometry and perspective. I'd love to hear what you think: Did it fool you at first glance? Would you like to see a version with a rolling ball? Feedback and suggestions are always welcome! https://makerworld.com/ko/models/2892999-impossible-slope-illusion#profileId-3232709

I designed a rubber band powered car that uses stored elastic energy for propulsion. Features: Fully 3D printable design No batteries required Powered by standard rubber bands Lightweight and easy to assemble Great for experimenting with gearing, traction, and performance I'm still testing different rubber band configurations and would love feedback from the community. If you print one, let me know: How far does it travel? What rubber bands work best? Any ideas for improvements?

I designed a compact bed scraper for removing prints from the build plate. Features: Dual-edge design for different scraping angles Two rear magnet slots (6×2 mm magnets) Can be attached to a printer frame or other magnetic surface Simple and comfortable grip The goal was to make a scraper that's always within reach instead of getting lost on the workbench. I'd love to hear your thoughts on the design and any suggestions for improvement. If you print one, let me know how it perform
