Dear @murrayjohnson @coco — does size matter? I’m not talking pies here, I’m talking helmets! As you are both acutely aware, I have no idea what I’m doing and it’s nearly Christmas. Fancy taking pity on a portly fellow?

Well I do like how this slicer software does supports…
Anyway this is the final piece before we can print actual proper helmet chambers. This should work, apart from the fact that it has a open top! I’m sending it complete with TPU gaskets and the original Lowther helmet.
You should be able to put it in place - 7mm gasket, driver, 1mm gasket, helmet. If you look closely, the gaskets have a straight part about 3cm long one one side, which should be aligned with the horn throat.
This piece should also help with alignment of the screw holes. Just put it in place and you have a nice vertical drilling guide. Although make sure that you do this with the 1mm rubber gasket installed.
My questions:
- Does it fit perfectly? Still easy to make adjustments.
- Is the height OK? Can be increased easily, if there is room
- I was concerned that the connectors on the driver would foul against the inner cylinder, part of the reason for doing this open piece. How much space is there?
- You’ll notice that I reduced the diameter of the cylinder about 4cm up (can be seen through the trees in the photo above). I’d rather do this more gradually, is there room for that? Thinking here about the driver connectors.
- The reduction in cylinder diameter is to allow easy access for the screws/bolts down, but it does reduce helmet volume. The alternative would be to have a larger diameter with long bolts all the way through. Preference?
Finalisation - I’m planning to make any adjustments from answers to the above, and then make a couple of minor changes to improve strength and ease of printing. This piece was printed with 15% infill, and I think I’ll do the final ones with 25%, so they’ll be slightly stronger (it seems to make little difference tbh). I’ll do them in black.

Supposing all goes well with Operation Helmet (that’s a lot of supposing), I still can’t place these fully into the corners of the room — which is where they’re designed to be to reinforce bass.
To that end, making a braced false corner for the cabinets is now on the menu. AI has unhelpfully and repeatedly failed to understand what I’m prattling on about, which is of little surprise, as I’m not entirely sure I do either.
See the red things here — like this, but not red, and not as shit and not in a corner already.

Would they not have to flare out at an angle like the wall would?
And extend further than the speaker?
Like, just be walls?

Not putting a corner horn into a corner will just lose a bit of the lower bass. With my Lowther corner horns it didn’t make much difference to 95% of the sound.
I can understand the playful element of putting the AER into the TP1 cabinet, but why not just stop there? If you want better, build a cabinet specifically for the AER? That front horn on the TP1 will really limit performance.
