To get the best out of 3D printing, it helps if you can design your own parts. In this tutorial series, we will learn to use a free 3D CAD program to do just that.
In this episode, I design a more complex part from start to finish to show the complete step by step process. This part is formed by using extrudes, revolves, sweeps and lofts. It is an excellent showcase of the workflow of parametric 3D modelling.

![How to automate everything in your yard - ESP8266 Arduino guide
I had some noisy goats who were making life miserable. My solution? Build a sophisticated system that can automate their food and water, plus control irrigation and provide video monitoring. In this video, I go through each part of the project, from setting up a WIFI enabled ESP8266 module in Arduino, to designing and building a largely 3D printed pet feeder and self cleaning water system. Everything is open source, so please follow the links below to use whatever is valuable to you.

![Full colour 3D printing at home with PolyDye - Open Source Inkjet integration
Check out my 2nd channel, TT Racing: https://www.youtube.com/@TTRacingYT
PolyDye is a community created solution to full colour 3D printing, by adding an inkjet cartridge controlled by custom electronics and firmware. In this video, I take you through how it works, installation and calibration, and current performance and issues. Hopefully some testers come on board to help develop and get this production ready.
The hardware in this video was provided free of charge for the purposes of testing and making this video. Although Jacques is my patron, I think it’s still clear that I have provided a transparent account of my experience, including bugs and problems.
I can only applaud the amount of work that has gone into this. This is such a huge and complicated project that will drive colour 3D printing forward for the community.

![E3D Revo practical review: Fast coreXY 3D printing?
E3D produced the industry standard V6 and Volcano hot ends, often cloned in cheaper 3D printers. Now they aim to take a step forward in convenience and usability. Is this at the expense of performance? In this video, I test the Revo system on a high performance coreXY 3D printer: the SecKit SK-Tank.
This product was provided free of charge by E3D for the purposes of review, in accordance with my review policy. All opinions expressed are my own.

![Plasticity may be the 3D design software you’ve been looking for
Check out my 2nd channel, TT Racing: https://www.youtube.com/@ttracingYT
The best option is always the one that works best for you. When it comes to 3D CAD, there are multiple approaches and some just don’t click for some users. So in this video, we showcase Plasticity, a new design software intended for artists with a freer workflow.
Plasticity is new and there will no doubt be plenty of development and new features to come. It’s also worth noting that there are always multiple ways to create the same geometry, so what you see in this video is not exhaustive of everything on offer.
