I’m working on a small desktop open baffle, single 3” full range speaker.
Is the shape of the front important or size of it ?
I’m thinking of making the front 6” wide by 8” tall x ¾” ply
And would bracing make any difference to the design as it’s so small?

You may do better to post in the Multi-Way forum instead, since that seems to be the location for all things OB.
I have done what you describe using a pair of Mark Audio Alpair 7P. You will likely need a helper woofer of sorts if you expect any bass at all (unless you listen from less than a foot away). My own micro-OB speakers offer almost no bass at ~3 feet distance, despite using a 12dB BSC filter plus bass boost on my portable music player. The mids and highs are quite nice, however.

Hi needtubes. its really only a test.. I have the drivers already and they are low budget, but apparently near-field. I have plans for a cube enclosure and a 3ltr to test what sounds good and what doesn't. Thanks for the input 🙂
Hi,
A total waste of time with that sort of baffle size,
build a sealed box, 2L to 3L for a typical 3".

While an interesting conversation could be had over "best practices" shape of enclosure, I'd avoid a cube if you can for anything but maybe a sub woofer. .
As to the question re bracing on a panel that size / application - not likely of benefit, although some short tapered side wings could supply not only required support, but a certain amount of improved at the lowest frequencies you're likely to otherwise achieve (circa 400Hz?)

If you are on a desk, there is a chance that this desk is near a wall.
If you are on a desk near a wall... sealed boxes will perform a lot better than OB.
Excellent feedback thanks .. skip the OB I think straight to a 6" x 6" x 8 @ 15mm wall sealed box according to the volume calc is 2.84 lts ish. Bit lest because I will brace the driver, haven't decided on a vertical or horizontal brace.. but I can try both I suppose.
