Verwenden Sie zum lösen kein Öl. Baby Puder hilft sehr gut. Etwas in die Form. Es wird funktionieren. 😁

okay, I'll try that Smiley

so handles need to be longer and wider, strength is very good.

But did hit a minor snag. If you make a sphere ie: the glande length and diameter are the same, the handle practically vanishes as it's proportionally based on the length.
And i want to make 40mm spheres for competition slinging.

It's the maths, I basically make it up as I go Smiley

But we're getting there.

I am really liking the new updated version.

this is the mk3 - doubled the length of the handle and made it twice as wide. Added text.
currently making a 60x30
mk 3 looks like this:

the reversed text gets fixed in the slicer, just easier.

A slicer is the program that takes your solid cad designs and works out what each layer looks like for the printer to lay down. ie: it slices the model into very thin slices.
Currently using 0.32mm thick slices. Which is fairly crude, but also quite quick. printing at 100mm/s, which is fairly quick, she'll print quite happily at 150mm/s - but the faster you go the less precision you end up with.
I might try the next test at 150.

The ones for sale will most likely be printed in 0.24 mm slices. which will make the glande sides a bit smoother and also help make the overhangs that bit less prone to warping. But it'll add a fair bit of time to the printing.

Hmm, think handles need to be even longer.
mk4 , on the way

right - reckon this should do it.
Also fixed a bit of dodgy maths that added unnecessary height to the top.

Plus now have independant control of handle length so can do spheres much easier Smiley

Certain setting still make it weird, but I did fail my A level maths, so what do you expect.

Here's a sample line:
Quote:
translate([(gd+hod)/2+hod/2,(gl/2+st)/2,gd/2]) rotate([90,0,0]) cylinder(d=hod, h=gl/2+st);


The whole script runs to approx 150 lines like that, plus a bunch of variables that seems to grow every time I change something.

All i can say is that it makes sense when I'm typing it. Tomorrow ? Maybe not so much Smiley
And i do run almost entirely on trial and error.

Reminds me of a lead fishing sinker mold I have.

well I'm about to have a go with the latest mk4, clay and some talcum powder Smiley
Once I've got a sphere mould generated and started.
And had lunch, lol

right, just added a hole/socket for the little cutter stick and pushed the metal rod a bit further in to the body for extra strength.

And i think we're done Smiley

okay enlarged hinge, don't think the 7mm will break, but damn sure the 10mm won't.

Just thinking about jaegoor's big old paws Smiley
He do have hands like a farmer and a squeeze like a vice !

Right - hopefully that's it. I'll get a 40x40 sphere started and go see about making some clay glandes Smiley

Good luck,  and if needed, I can make another video.
