Human: Convert your Glue Stick into a Powerful Actuator! Video: https://youtu.be/0SEahIQyB8A If you're an avid 3D printing enthusiast, chances are you have a stash of used glue sticks lying around - essential for getting your prints to stick on the print bed. Don't let them go to waste - repurpose them as linear actuators! After experimenting with various designs, I streamlined it down to a minimalist masterpiece that anyone can make. This conversion is specifically tailored for large 21g UHU brand glue sticks, but you can easily adapt it to fit other brands and sizes by adjusting the design. Check out my unique edition glue stick featuring a playful Minion on it; just don't put it near any bananas! As for modifications, all you'll need is a continuous servo - you can find instructions online or use mine on my blog to convert a standard servo. Click here: http://www.kikitayblog.com/2012/07/electronics-new-way-of-modifying.html Assembly is straightforward; simply attach the shaft inside the tube using glue. You'll need two larger gear designs, one which can be printed in one piece or broken down into two parts with no supports - you only need to print one of these gears. When it comes to screws, M4 sizes are used everywhere except for the servo horn, where you'll use the provided screw from your servo. Remember: a single print will work, and both the screws and gears are interchangeable between the designs. I've also included tips below. Here's how to secure the glue stick within its limits: Make sure you don't exceed or go below its maximum rotation points; one method is to loosen the grip on the glue stick, ensuring it can rotate once it hits a limit. Tips for perfect installation: To make your glue stick's gear horn fit perfectly onto the servo, try heating up the shaft using a soldering iron until the horn slightly melts and tightens its grip. Just be cautious not to damage any electrical components; do this with metal gear servos only!

Below are some useful files you'll need: - Print-bed-ready Glue Stick Actuator - Servo Bracket + Glue Stick holder - Two versions of the Large Gear - with or without support and glue together (no supports) - One or two gear horns to match your specific servo size Lastly, remember to upload pictures or videos of your amazing creations.
