![Answering your CAD requests - 3D design for 3D printing pt9
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 fill in some blanks by showcasing some features requested by viewers. We cover organisation, the revolve and sweep tools, advanced fillet and chamfer options, organic shapes with surfaces, export to DXF, surface textures/patterns and how to avoid support.
A future video is planned where I design a more complex part from start to finish to show all of the little problems and how to fix them.

Check out my 2nd channel, TT Racing: https://www.youtube.com/@TTRacingYT
I’ve seen people complain in the comments that new age 3D printers like those from Bambu Lab are hard to work on, with components hidden in hard to reach areas. In short, these machines are not designed for disassembly and reparability in mind. In this video, I undertake a series of fixes in Bambu Lab printers and compare the process to more traditional designs.

![Hero Me part cooling system - Modular, capable and super compatible
Check out my 2nd channel, TT Racing: https://www.youtube.com/@ttracingYT
Previously, I had invested quite a bit of time and effort into modifying a Creality Ender 5 to have an enclosed and actively heated chamber. The addition of the Bambu Lab X1C to my studio has made the Ender 5 redundant, however, so in this video I remove all of the heated enclosure parts, and fit the Hero Me gen 7 part cooling system.
If it feels like at some times I’m being vague, that’s on purpose. The documentation is thorough but not free, so I had to make sure not to make it redundant. I’d recommend anyone undertaking this upgrade, to pay for the detailed PDF guide at a minimum.

![Flexible CAD designs using variables - 3D design for 3D printing pt8
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, we explore the concept of variables in CAD. By creating a named value outside of any sketches or features, we can then reference that value and use it to drive geometry. If the design needs changing, only a single variable needs editing rather than going through and editing each feature. Variables offer an efficient way to make your design flexible.

![Conditional PID tuning for maximum hot end stability - Is it worth it?
Check out my 2nd channel, TT Racing: https://www.youtube.com/@TTRacingYT
I personally only tune my hot end PID for a single temperature wit the part cooling fan at 100%. But perhaps a lot more accuracy and stability can be found with conditional PID tuning. In this video, I take you through what PID is, how to tune it, and how to tube it for various scenarios and apply the, in the slicer. In theory this is superior, but in practise the effort may not be worth the meagre returns. What do you think?

![Resin 3D printing beginners step by step guide
I often hear the same statement: ‘I’m interested in resin printing, but I’m not sure of all the steps and whether it’s for me’. This video aims to respond to that situation. There are multiple ways to approach resin printing, but hopefully my methodology provides some food for thought for others setting up.
Thanks to my patrons for sharing their tips and workflow in the preparation for this video.
In regards to safety, everyone will ultimately make their own choice on the measures they adopt. My advice would be to treat resin with tremendous respect and assume the worst case scenario. Plan for the worst, hope for the best.

![These 3D prints will convert non believers
Some people think 3D printing is a useless technology and hobby. Quite frankly, they are just wrong. In this video, I present a range of 3D prints to convert non believers. While not every 3D print is useful, many 3D prints have a positive, meaningful impact on our daily lives. This ranges from convenience, hobbies and even life changing medical technology.
The next time someone dismisses 3D printing as a meaningless activity, send them to this video.
