On another note... I've decided not pursue the flexi arm solution because you can buy these setups already on ebay for about £8 from China! I will probably make one for myself but I won't offer them to anyone as I can't make them cheap enough. I will be sticking to the mounts I already make but I'll probably tweak them a little.

I was looking at the new diffuser that Canon is bundling with the MMT-26 EX RT and wondered if you could 3D print a diffuser that could be glued to the Canon one? The new indentations on the MT-26 might allow for a heavier diffuser without having to use a strap if the diffuser can take advantage of the new mounts on the flash heads.

Yes that is most likely possible, I'd have to see what the diffusers were like first. However gluing isn't really the nicest way of attaching them, especially if you want to change something. If not the straps I am using are by far the best way I've found of attaching them so far as they hold the body really tight and are virtually indestructible!

What do you think of the stock Canon diffusers? They look like Gary Fong knock-offs to me from the images online. -?

More like a Sto-Fen but with a bigger clip on the side to hold it in place, maybe a little more opaque, and it looks like there is more contact between the diffuser and the flash heads. Looks more mechanically sturdy, but I doubt that the diffusion will look good unless you're shooting at 4x and higher with the MP-E 65mm.

Yeah, that's what I thought. But the attachment points on the heads might serve well for DIY diffusers.

That's what I'm hoping.

Sorry for the lack of updates. Unfortunately after being unwell, it ran into the busiest time of year for me in my business so I've had to put development on hold for the time being.

I hope to get back onto these in the next week or so, plus I've been testing some new materials on my printer (when I get a minute!) which I think will improve light output even further than what they already give. Yes I know I still need to do that test for you John!

Ok, I've finally got around to doing some bare flash vs diffuser comparison shots. From these results there seems to just a loss of of about 1 stop. With the extenders added I would say there is only a loss of about half a stop.

Shipping for current orders now show in the Jan/Feb timeframe. I ordered mine 10/6, and per their support, I should get it before Christmas. I already have a large box of PLA spools from a Monoprice deal where you buy 4 or 5 and get one spool free.

Yeah I know a lot of people have sold their MK2 for the MK3 so there will be a backlog due to the amount of people ordering. I should hopefully get my 2.5 upgrade before xmas but on my other printer I'm probably going to upgrade it to a Zaribo version before I upgrade to 2.5. Zaribo is an upgrade kit with enhanced parts and an aluminium frame extrusion, similar to the MK3 but bigger.

I do need ot buy a 3rd printer at some point because when I get orders for my diffusers, both my printers are running full time for about a week and I don't get chance to use them for anything else!
