Do you have longer TPU bristles designed yet for LR4 dust shoes? I think you had mentioned it as possibility. I checked the Printables but only saw 22 mm there.

Yes thank you! I was just thinking about that this morning!

What is your endmill stickout and ultimate depth of cut? I am not interested in Mods until the instructions are done but we will get there. Give me your dims and I will keep a note.
Just to be crystal clear here. With TPU You can not just use a long bristle to solve issue it is tuned to how you cut. Super long and they are just going to suck into the vacuum. On a long bristle there will need to be a rigid part at the top before they get loose again. Do this wrong and you will drag and push on the router and lose accuracy, or get poor suction.
The ones I made are for up to 17mm DOC Standard stick out for all the endmills I sell.

Good points. I think my 1/4" end mill is not as far up in the collet as normal (down by maybe 3-5 mm), plus my dust shoe is mounted a little higher than normal, so those factors combined have me seeing about 1/2" of bit sticking out below the bristles. I can fix some of that by getting the bit a little deeper into the collet. Due to how I have my shoe mounted, I probably ought to think in terms of a set of bristles that are longer by some 5-8 mm. I’m typically cutting 19mm deep (3/4").
Start there. All endmills should be as deep as possible at all times.

Will do.
Just curious since you mentioned it, how important is the location of the end mill in the collet, as in if it is pushed all the way up or if it hangs out a bit?
My understanding is that to do full depth cuts you need all the cutting blade portion showing, but no more. Having more stick than is needed leads to more potential for deflection (“CNC-ese” for bit bending). I guess if you are not needing full depth cuts, you could put the bit even deeper into the collet, kind of like “choking up on the bat.”

Always as deep in as you can go.
The more it sticks out the “longer” your Router becomes, the more the load is multiplied, the slower you need to go to maintain the same accuracy.
You can not cut any deeper than the flutes on your end mill so hanging it out does not gain you any depth abilities.
In metals, or super long bits in wood/plastic, tool deflection is also a concern. Shorter is better.
