Ender 5 enclosed lid and heated chamber guide

My modification of the Creality Ender 5 continues! The aim is to enclose it and heat the build chamber and be able to print high temp engineering plastics that usually warp and delaminate.

In this video, I design and fit a custom handle, construct a removable lid with 2020 extrusion, acrylic and printed parts, and fit a chamber heater. Everything is shown step by step with instructions on configuring Marlin firmware. Printed parts are below.

There will be a follow up video showing the final versions in action printing Nylon, Polycarbonate and ABS.

Some notes:
- With the lid the chamber hits just over 40 deg C without the chamber heater on.
- The chamber heater only adds a couple of degrees.
- You need a high power heater to be able to heat the chamber up to a useful temperature.
- The heater I put together is under powered, but still adds load to the mainboard MOSFET and PSU. It is better to remove some of that load.
- I have mans powered bed on the way. This means I can free up the PSU and heated bed MOSFET for a more powerful chamber heater.
- I could alternative run another solid state relay to switch on and off a mains powered heater based on a hair dryer or heat gun. This will be efficient but adds safety risks.
- At higher tempos I will need to insulate parts of the enclosure, such as the PLA printed electronics case.
- My torture test is very difficult for ABS. Pointy edges but a tall and bulky middle section is very prone to shrinking and curling up.
