When I first started 3D printing almost a decade ago, I was captivated by the endless possibilities of turning digital designs into physical objects. Over the years, I’ve tested countless gadgets, tools, and upgrades, hoping to streamline the process and improve results. Most turned out to be overhyped, but two stand out as genuine game-changers: OctoPrint running on a Raspberry Pi and the Sunlu Filament Connector.
1. OctoPrint: The Ultimate Print Manager
If you’ve ever felt tethered to your 3D printer, constantly checking on progress or manually managing settings, OctoPrint is the upgrade you need. By running OctoPrint on a Raspberry Pi, I gained complete remote control over my 3D printer. Here’s why it’s a must-have:
- Remote Monitoring: Keep an eye on your prints from your computer or phone with a connected webcam.
- Seamless Workflow: Upload files, start prints, and adjust settings without constantly transferring SD cards.
- Time-Saving Plugins: Automate bed leveling, filament changes, and even power off the printer after a print.
- Error Prevention: Detect and stop failed prints before wasting hours or materials.
OctoPrint isn’t just a tool—it’s like having a personal assistant for your 3D printer. It’s especially helpful if you’re juggling multiple projects or want to monitor prints while you’re away from your workshop.
2. Sunlu Filament Connector: Goodbye, Waste!
If you’re like me, you’ve got a drawer full of filament scraps that are too short for a full print but too valuable to throw away. Enter the Sunlu Filament Connector, a deceptively simple tool that lets you fuse these scraps into usable filament.
Here’s how it works:
- Insert the ends of two same-material filaments (e.g., PLA to PLA) into the connector.
- Heat them until they fuse together.
- Trim and smooth the joint, and you’re left with a continuous strand of filament.
This tool doesn’t just save money by reducing waste—it also opens up creative possibilities like combining colors for unique prints. Plus, it’s perfect for smaller prints where the fused filament can be used without issue.
Why These Two Upgrades Matter
OctoPrint and the Sunlu Filament Connector solve two common pain points in 3D printing: efficiency and material waste. With OctoPrint, I’ve drastically reduced the time spent babysitting prints, freeing me up to focus on other projects. Meanwhile, the Sunlu Filament Connector has helped me reduce waste and experiment with creative prints.
Both upgrades are simple, affordable, and incredibly effective—proving that sometimes, it’s the small changes that make the biggest impact.
What Are Your Game-Changing Upgrades?
These two upgrades have transformed my 3D printing experience, but I know every maker has their own favorite tools. What upgrades or tools have made a significant difference in your 3D printing journey? Let me know in the comments—I’m always looking for the next great idea!
