Review on 🖨️ Advanced Display for SCRIB3D Printing Pen by Rusty Calcara

This is the first 3D pen I have bought. That being said, I found the instructions quite clear and the handle quite comfortable to hold. Loading threads was pretty easy. BUT. This type of tool requires a serious learning curve, lots of experimentation, and an initial waste of filament. Here's my advice: buy extra filament (PLA) when you buy a pen. The pen comes with a small amount of thread. Not enough to learn how to use this pen. Watch many YouTube videos on this and other 3D pens to understand the concept and reality of using this type of pen. Commercial videos embellish reality and don't tell you that you have to spend quite a bit of time and money (per thread) to get something satisfying, especially if you want to build 3D structures. You don't have to build an impeller (sort of) from scratch. Others have gone before you, suffered, and found ways to minimize that suffering. Benefit from their history. Note that you will need to open the handle from time to time to remove the stuck filament. The design of the handle necessitates this due to the way the thread enters the handle. You can't use short lengths of filament (shorter than the distance between the feed mechanism and the front of the pen. If the filament disappears into the pen and goes past the feed mechanism, it will get stuck. Opening the pen isn't too difficult, but you don't want to stop there when you're on the go. Overall, this pen is very similar to others but has some great features that allow you to adjust the temperature of the pen and choose between two types of common filament: ABS and PLA.Choose PLA because it's less toxic I would recommend this warning pen.
