3D Printing hot end upgrade

3D printing is great, isn't it? Until you run into your first issue (this hardly ever happens, right? right?).

Had my first hot end disaster, started a print, walked away... forgot to check 1st layer adhesion... Oops!

On to amazon to order a replacement... wait... are there any better hot ends for the Elegoo line up? There are! I'm going to be trying out this one below.

Bluetooth OBD2 reader

Along with all of my tinkering with 3d printing and woodworking, I also maintain all of my own vehicles. What is the first thing I'd recommend anyone has? A decent OBD2 reader!

If your check engine light is on, you'll be able to see the error codes stored. The BlueDriver app will give you a list of solutions to repair your car. Sometimes it might be out of your capabilities, but what if you could replace a simple part and save yourself hundreds at a repair shop? This device will pay for itself!

I just recently designed and printed a case for a basic model rocket launch controller. Very simple design, key for power, and various LEDs to indicate status (power, continuity, launch ready).  Added a voltmeter to let the user know there is enough power in the batteries to make a launch. Will take some pics, and of course get the models posted over on Printables for you to download and use or remix!
