This is as hand-wavy as it gets, because nearly every single part of this
project is configurable to fit whatever parts you have on hand, and the quantities
of some parts depend on the build size.
Unless you've changed some internal parameters (in parameters.scad instead
of parameters-sizing.scad), the bolt lengths should stay the same.

| LED mount clamp & pad | As needed |
First, you need pick the sizing parameters for your build: chamber height and
bed diameter, as well as LED strip width and thickness.
Open parameters-sizing.scad and edit the relevant variables.
After you've edited parameters-sizing.scad, you can build the STL files by running
./scripts/build. This will create STL files in the output directory.
If you've changed any internal parameters, here's where to look for new bolt lengths. These will be output by OpenSCAD, albeit repeated a couple times as the output renders.
- Material: Any material for everything but the cover and LED mount parts. Use PETG for those - the chamber may get toasty inside.
- Layer height: At most 0.2 mm layer height (recommend using variable layer height with adaptive layer height, which will use different layer height for the base and the hinges).
- Infill: 15%
- Perimeters: 3
You'll need to connect the toggle switch and the mechanical endstop switch in series with the LED strip.
- Insert the 4 M3 nuts into the nutcaches in the bottom of the floor.
- Insert the 10 M2 and 4 M3 nuts into the nutcatches in the base.
- Mount the PCB on the PCB mount, to the base. Leave the switches and LED strip unmounted for the time being.
- Mount the LED mounts to the base.
- Insert the 2 M3 nuts into the nutcatches in the bed mount.
- Mount the bed mount to the base. Don't mount the bed yet, it's going to get in the way of mounting the LED strips.
- Insert nuts into nutcatches on the LED clamp pads. Insert the pads into the channel on the back of the LED mount, and the clamps on the front. Join them together through the hole in the LED mount with a M2 bolt. As you tighten the bolt, the pad should rotate in place.
- Start wrapping the LED strip around the chamber by inserting the strip into the clamps.
- Mount the cover with the 4 M3 bolts, mount the toggle swich (through panel) and endstop (with M2 bolts) to it.
- Put the cover top on top, and you're done.
