After some AliExpress searching, I'm thinking that an alternative could be a CR10 heatsink cut so that it's 15mm in height along with a bimetal heatbreak.
This combination would be a comparable to the price of a single MQ Mozzle heatbreak.
- The filament would be less constrained.
- It could make manufacture more tedious. It looks like there wouldn't be that much material to cut through and the fins should act as a guide for the sawblade, so I have hope that it should be very straightforward to do.
- It's technically would be heavier too, but I'm not one to be chasing grams.
- I've never tried the titanium alloy bimetal heatbreak and only have experience with the copper threads version, and I suspect that clogs could be more likely and lower flow rates.
- It works and I can have the option for using normal length or volcano nozzles as intended.
- The parts would likely be easier to source, especially considering if the cheap Mozzle heatbreak would still be around in a few years.
- May be easier to securely fix into the Slight due to the larger surface area on the sides.
- Use a more expensive version of the MQ Mozzle throat?
- It doesn't seem like any of the £3 - 10 options would have the 5mm long threads, and I'm still trying to go for a cheaper (and lighter) option to the metal BMG hotend.
- Use an aluminium hex spacer for M7 and stick heatsinks on the flat surfaces.
