It’s a very nice design. It looks modern and ergonomic. It also appears to be nicely proportioned relative to the knot. It’s very fun to see the prototyping process.

I had some time this weekend to put a knot in the grey handle.  Truth be told, I moved the knot from the white one to the grey...this knot is getting a bit ragged as it's been in about 4 different handles as a "tester".  Still a very nice feel to it.

Here is the knot and handles.  The red disc on the knot is a silicone shim I cut to get it set at the right loft.

And with the knot temporarily set using some clear silicone...

...and who would've thought that the handle design would make a decent brush holder...ala SV...

I used the brush this morning and it performed very well.  Despite it's raggedness, the knot is still very nice and the handle fits well in the hand.  I am going to continue test driving it this week...

I put the brush through its paces over a week period, including some travel time.  I was very happy with the brush performance and the fit and finish of the handle.  The handle itself is a bit light as it is hollow, but that didn't bother me...particularly when traveling.  As I indicated before, I'll experiment with filling the hollow part with epoxy and maybe a ball bearing to give it some more heft.

In the midst of these experiments, the opportunity arose for me to put together a brush for a special occasion.  I made a few modifications and sent the model off to the printer.  More on that later as it progresses, but here is a quick picture, hot off the press...

Awesome progress, Tom. What resolution is that printing at? The finish looks quite good.

Thanks gents.  Appreciate the comments and I'll keep the updates coming.  As for resolution, I'm not sure what it is...I'll confirm with the printer.  I basically asked for "as smooth as possible"!  Smile
