Dude, these look great. Exactly what I'm looking for. I'll be considering these for a few upcoming builds.
There are two types of people in this world.

1. Those who can extrapolate from missing information.

The cell holders showed up and look excellent. You do need to pay attention to make sure that all of the dovetail joints are properly connected, and the shipping was quite expensive. Once the package left Poland, which took around a week, it was here within a day and a half (Houston, TX). They are exactly what I was looking for. Thanks again.

Few days ago we have finalized machining of injection tool and did trial for x2 holder. This one, compared to the one from my latest post, has dovetails around all sidewalls and can be used in the middle of the honeycomb assembly.

The previous type had no dovetails on a sidewall and shall be used to terminate the honeycomb assembly.

We are doing further research and I will keep you informed on new solutions!

Sure - I'm looking at building a drop-in replacement for the iMiEV battery, except with 18650 cells and liquid cooling. 24 kWh would be easy, 27 kWh might even be possible with a bit of shoe-horning.

Here's what my two half packs look like with all the holders assembled. It can be a bit of work getting the holders all the way seated, but they are a great design. I used the three cell pieces for everything but the last row on the larger of the two packs in which I used the two cell sections. Thanks again.

How to estimate how many and what type of holders you need for your application??

There are two ways to get the answer:

**One is to estimate the number by following formulas:

NumberOf3xHolders = (2*NumberOfCells)/3
NumberOf2xHolders = 0.1*Numberof3xHolders
NumberOf1xHolders = 0.1*Numberof3xHolders

This should cover safely most layouts.

**The other one is to print out this 1:1 pattern on A4:
HoneyComb Holders Pattern 1to1 A4.PDF
(675.05 KiB) Downloaded 151 times
and follow the example:

You might need few copies sticked together to cover bigger footprints.

How does one order these? The OP mentioned "PM" which likely means "send me a message on another channel", which isn't terribly useful. I guess I'll be buying that Makerbot after all ...

Yep. I just received my order of 1000 triple hexagons. Pretty convenient way to put a pack together.

If I want to do a 15s14p = 210 cells battery. I need 2*210/3 = 140 holders (3x)

140*.12€ = 16.8€ total cost?
