Real simple one.

Has anyone found a passive cool box that fits nicely in the boot well of the Model 3?

Looking for something that will fit nicely in the boot for when I go on a driving holiday and we take food etc to keep it from warming up too quick.

Cheers.

There’s a new product coming soon from CNCT coolers (pronounced connect) from the US. They’re on Twitter @cnct_coolers if you fancy checking them out 👍🏻

So checked out the boys at cnct_coolers and they are starting pre-sales tomorrow. BUT...
They gave out a 20% early bird discount which equated to $60. $300 for a cool box. No thanks. Even with 20% off at $240 that's way too steep for me.
So far I've not found anything that isn't either too tall or tiny, so not worth it. I think I'll make one to suit out of some wall insulation and mdf. Reckon I can do a pretty neat job as well and it'll hold a lot more volume.

What about a traditional camping cool box?
I've trawled Amazon, Argos etc. I just can't find one the right size. Either tiny or far too tall. I want to be able to put the cover back on the boot well.
Will just go for a soft bag for now and then look at making something. Will be a nice project.

Interesting idea.

Based on something I made in the past, I think mdf will make it uncomfortably heavy, but I think I know what to make it from.


Aka Correx, this stuff is light, cheap and super-easy to work. Cut out a simple net, compress along fold lines and it will fold easily. Glue with cyanoacrylate to make the "tub".

Then I'd probably use EPS sheet, 25mm thick, for the insulation - Jablite Polystyrene Insulation board (L)2.4m (W)1.2m (T)25mm | DIY at B&Q

For sticking that to the correx, this would probably work (and what I use for sticking open-cell foam sound insulation to correx): Evo-Stik Light amber Carpet Adhesive 500ml | DIY at B&Q

Then line the inside with another layer of correx and then cover the insides, especially the seams, in several layers of Aluminium tape: Diall Clear Aluminium tape (L)50m (W)75mm | DIY at B&Q to seal the insides as best as possible (ie to prevent any leakage of condensation etc).

Obviously a lid with similar construction.

This would be much lighter than MDF and also would be much more resistant to liquid spills and condensation.

In fact rather than messing around with EPS board and adhesives it would be even easier to make the inner and outer correx tubs and then fill the space between them with expanding foam - this will act as the adhesive and has excellent insulation properties. It would also deal well with leaks/condensation as the expanding foam would not allow a path through for water.

You could go even further than that - simply make the inner correx tub, then put plastic sheeting into the under-floor well and fill with expanding foam - that way the foam will mould itself exactly to the shape of the under-floor tub. Riskier, but would make a perfectly moulded "to fit" box. Of course, then the inner box wouldn't need to be correx, but you could buy whatever plastic tub that is the closest fit to the underfloor space.

Hmmmm.... Now I want to try this!

I certainly found that putting frozen and refrigerated foods into the underfloor space during a shopping trip kept them cooler for longer, so turning that underfloor into a cool box would prove useful I think.

Nice one, cheers for the tips.

MDF was just a top of the head thing. What you mentioned is much better. Also probably better for the lining of the well.

I'm actually tempted to do the expanding foam method and then carve out a box and then line it. I'm going to give that some thought
