Sorry guys I have been busy with work (have to put food on the table, and this is just a hobby and I am just trying to help out fellow hobbyists when I can).
I have 3d printed FFF on ABS about 15 sets of 7-spoke spacers if people are still interested. The first 16 PMs or so will get a link to purchase, at least until supplies run out. Cost is $30.00 for 3x spacers and 3x o-rings, or $40 for 6x spacers and 6x o-rings, and a flat $10 usps priority mail with tracking to continental U.S. either way. Maximum of 4 sets (12x spacers and 12x o-rings).
To be clear, a set has 3x spacers and 3x o-rings. You can purchase up to four in U.S.
$40 total (cost + shipping) for 1 set
$50 total for 2 sets
$70 total for 3 sets
$90 total for 4 sets
I designed and printed some of these V2 spacers for my FX Crown MKII with CF barrel sleeve after I couldn't get danny5692’s design to print well (edit: This design https://www.airgunnation.com/topic/carbon-sleeve-fx-crown/#post-1164001).
The purpose of these spacers is to center the barrel with the CF barrel sleeve within the FX Crown shroud, which I believe essential. These spacers fit the .177, .22, .25 and .30 CF sleeves, and fit between the FX CF barrel sleeve and the FX crown shroud. The CF barrel sleeve stiffens the barrel, but without spacers, the floating barrel and CF sleeve are not held fixed to the shroud.
Here is a photo of the set of 3 spacers and o-rings (latest 7-spoke design) taken today.
These spacers and o-rings come with details on how I used them, with warnings, cautions, etc. Use at your own risk.
Here are some other photos to illustrate the use:
When installing the CF Barrel sleeve on the FX Crown barrel, you may decide to use electrical tape to affix the CF barrel sleeve to the barrel, or use Teflon, or to epoxy it to the barrel. I ultimately decided to use epoxy (Infinity Bond EP 420 High Peel and Shear Strength Epoxy - 25 Minute Open Time) as it is slow curing...I waited a day before I installed the spacers and shroud. You can see some of the epoxy in the above photo.
However, this is a rather permanent solution so you might want to try it with Teflon or electrical tape first.
Below are photos of earlier designs (5 spoke) design

I haven't done formal testing on my setup but I have taken out some pests. That is a time where I went the "it is self-evident" to improve things route.
