I own a five tool Prusa XL, which is now working pretty well. For many people though, this 3D printer is just too expensive. In this series, we are attempting to take a StealthChanger toolchanger mod intended for the Voron 2.4, and adapt it to the Sovol SV08 Voron clone. In this episode, we tidy up some loose ends and finally print and assemble the coupling mechanism to allow toolchanges.
Still no parts released, but that is simply because there will no doubt be further refinement and iterations.
This printer and the additional toolheads were received free of charge from Sovol for the purposes of making this series. Everything else I’ve paid for myself.

![PHA filament - Mostly superior to PLA and actually eco friendly
Check out my 2nd channel, TT Racing: https://www.youtube.com/@TTRacingYT
I’ve made a series of videos about recycling because I care about minimising the environmental impact of my 3D printing. So when my patron NovaPlusPlus informed me about PHA filament, I immediately purchased some to test. In this first part, I compare PHA to PLA, seeing how hard it is to transition, as well as testing the properties of the two. PHA comes out ahead in every area except one.
In a future video, I will share the results of long term testing. Does PHA hold up in normal conditions, and does it biodegrade as advertised?
I purchased this filament with my own money. All onions expressed are my own.

![Creating sloppy parts to ensure perfect fit - 3D design for 3D printing
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 demonstrate two projects with geometry that needs to be spot on. Rather than design and print over and over until the fit is perfect, I demonstrate purposely creating pas with too much clearance that can be bolted into the perfect place once in position.

![Orbiter Filament Sensor guide - A smart, automated way to improve your 3D printer
Filament runout sensors can save you from ailed prints, but they are a pain to deal with otherwise. My patron Derek shared the Orbiter Filament Sensor, which makes loading and unloading easy with automated processes, plus covers the usual runout detection. In this video I show you step by step how to print, assemble, install and configure Klipper to use it. This includes understanding the macros so you can customise to suit your printer.
Thanks to the creator Robert Lorincz for their work and for making this open source. The concept should be easy enough to adapt to other machines without an Orbiter extruder in place.
