Introduction: But why? Lets be honest- recursion is fun. That's why I created the Prusa Micro! Its a tiny model roughly based off of the Prusa Mk3s that “prints” along with your printer! While rotational movement as an indicator is fun, I thought it would make for a fun challenge to create something that converts the rotational motion of the stepper motor to some sort of linear motion. As a result, this indicator was created as I love myself a little recursion. Now, I don't personally own a Prusa printer as when I was shopping around for a printer I wanted to get something on a hardcore budget. As a result, I don't 100% know if this will fit or work with a Prusa Mk3s or Mini. However, if you do end up printing this, please let me know if it works! Now for the assembly instructions. Step One: Attach the wheel to the stepper First off, you want to grab your stepper. Don't worry, you don't need to remove it. The wheel is the first thing you'll want to attach. There are two methods for this, but I've only tested the first one. You can hot glue the wheel on - in that case use “Wheel - Adhesive.stl”. I have tested this and it works well! You can use an 8mm magnet - in that case use “Wheel - Magnet.stl”. However, I haven't tested this yet due to: not having a stepper with a flush axle pass through on the back, and not having an 8mm magnet. If you do go through on this method I would really love to hear your thoughts and whether or not it works. Now, you just have to attach the wheel roughly in the center. Doesn't need to be perfect, but should be as close as you can get it. It should look like the photo below at this point. Step Two: Ensure the slider and body actually fit Now, grab the body and slider that you printed. Check to make sure that you can easily slide the slider through the cutout on the body. If it seems a bit sticky, try sanding the track inside of the body and the slider a little bit. Once it slides well enough for your liking, move on to step thre
