Also bear in mind how much easier it is to use a staff sling with gloves on Joe

Snowballs !
Got all my broom handles just before Christmas.
Really nice, all I've checked so far are straight with no large knots. Quite impressed.
Currently working on two different ideas.
One is a standard printed head that takes different inserts.
Figured easy to exchange tips held in with a through bolt, might be an easier way to do it.
Currently using laser cut '3' mm ply.
The problem is that it's not actually 3mm and I didn't measure the exact thickness, before printing the first broom top.
Cut a hoopak tip.
It's nearer 3.5 and will not fit.
Plus arms need to be wider and longer.
The 3d printers are actually a lot more dimensionally accurate the the laser cutter.
That's got the world's cheapest controller board, really suffers in cutting accuracy because of it.
Image engraving is spot on. Soni know the actual mechanics of the machine are fine.
Just the way the board drives the stepper motors for continuous cutting or engraving is pretty iffy.
I do have some 3mm acrylic. But while really stiff, it is extremely brittle and I reckon plywood is probably a better bet for a staff sling. I might try it.
So currently reprinting the broom head with a wider insert socket.
I also need to make the tips a bit bigger.
I might also try a straight printed insert.
Although using inkscape to draw a 2d outline for cutting, is actually much easier and quicker. Than creating a 3d model with openscad.
And it's only just occurred to me that I can take that 2d drawing and extrude it into a 3d model duh !
Well that will certainly make printing the inserts a lot quicker and easier

The head hammers on to the broom handle no problem. And I've put 3 screw holes for permanent attachment, although as I have to also use a hammer to remove the head, not sure screws are strictly necessary, and 1 would probably be sufficient.
There's also a through hole for a bolt to hold the insert securely in place.
The other idea would be like kordwars, and an all in one socket and tip.
As I'm currently using polyurethane - mainly because it laughs at hammers.
Not sure if the tips of a hoopack would be stiff enough.
So that needs testing.
Right took some pics, so I'll go sort those
