Low-cost copper pills, spacers, optics, drop-ins (Updated 23/10/2022))

Would it be possible for you to make this spacer for the Convoy S11 host in copper?

It was designed by a Reddit user named DE-173 in this post. and they were kind enough to share their design for the spacer.

I have host on hands and can do a sample if you need.

Lets make it happen :slight_smile:

Is there any need for M2 quad spacers if I will make S11 full height quad pills?

Better wait for S21A.

S21A should fit triple optics, not quad.
S11 is great out from the box. If you want custom leds and driver, youd probably move from ugly XHP tint to 4 smaller but more pretty leds. So you need spacer. If I went with my regular quad design (Cu spacer+brass liner ring), this would cause too many parts that have to be put under stock pill (also youd probably use 17mm driver so extra adapter was necessary). I think full height aluminium quad pill with 17mm driver place is good consensus, not so heavy, not so expensive, not tricky for build, better thermal transfert, no need in extra adapters. Also full height pill design is easy both for upgrade and downgrade - this is not common for S2+ (smaller size+similar drivers) but should be cool feature of S11. Just have two sets - stock pill with reflector and quad pill with optics. And change between them when you need.

I’m in need for a 18650 quad host and was wondering if the Sofirn SF36 would not make a better host than the Convoy M2 since the SF36 with XP-L HD is regularly on sale with a reduction, actually US $16.95.
If not, I will go for the M2 spacer, 3 or 4 units (in aluminum).

One M2 kit (copper spacer) available.
I have build SF36 quad once. But sofirn is not convoy, they used to change flashlight dimensions occasionally. I need to find my drawings and measurement and compare them with hosts that are sold nowadays. Hope some thread subscribers could help with measurements.

90g of copper spacer for a quad S11 build I’m piecing together:

Still have some C8TT heads. For those who are not satisfied with 3 led version, I can mod them to accomodate 40mm anna-6(7) optics:

Now this is tempting but I’m out of my C8 hosts. Hmmm

And yes, I still think that full head design is usefull feauture because you can swap heads.

What would it add the the cost of the C8TT?

$5.

I assume it can’t be re-threaded for the 21700 C8, right?

Right.

What is the total price modded for the 40mm anna optic and rethreaded to fit Convoy M21A threads?

Is the anna optic included or do we need to buy them separately?

No rethread option.
Optics and pcb are available from led4power.com
Set:
Alu head modded for 40mm optics
Brass retaining ring for 17/20mm driver
Cu spacer
Stainless bezel
AR coated glass
O-rings
$31 without shipping.

Do you have any C8 spacers individually? I have a Manta Ray C8.2 which takes Convoy C8 reflectors but also has a head that is almost double the mass.

No. Can try to make one if needed.
