Nice one Joe !
Staff slings are a whole different process.
The best thing about them I find, is that the missile always goes forward. (Or straight up

)
Release is controlled by acceleration. And that's all you ever need to change to hit anything.
They are the ideal sling for people who lack any kind of hand eye coordination.
And we've all had 'pupils,' like that.
In many ways, it would make more sense for people to start their slinging journey with staff slings and then move on to hand slings, rather than other way round.
Fascinated to see how you get on with them

@kordwar
Resin machine coming this week, so I've been cramming all the new stuff over the weekend.
Presumably you printed the heads with the threaded hole facing downwards, so the resin could drain ?
How easy is it to remove the supports ?
Or am I missing something obvious ?
If you punched a hole or two through the model so resin could drain from the top, would that make it easier to post process and reduce resin wastage from the supports.
Or, again am I missing something

Starting the 3d printing journey over with a completely different technology is kinda cool.
Although I have just realised that I'll need some way of levelling the machine as not one single surface in my workshop is actually level !
Something irrelevant for fdm printers.
