about halfway through a shaped roller design.
Probably have some time to do more tonight.

Anybody know how to work out the volume of an ovoid ?

My original thought was to work out the volume and then make a square frame of that volume to measure the starting amount of clay in.   
But after thinking about the maths figured that was way way too complicated.

So the easiest way I reckon is to make the first glande the long way by adding a little clay at a time.
Then when you've got it right - weigh it. And use that weight for all the rest.
Which is quick and simple

Currently printing a trial roller for small 30x15mm glandes.

The idea is the sticky up tabs at the ends keep the thing centered while allowing you to slide it almost the entire length of the bed.
I figure stick a weighed lump in the middle and then roll back and forth with gentle presure till the edges meet.
Should give you perfect glande every time and be pretty quick.

It's a parametric script so i can generate any sized glande, Well within reason, I have to be able to print it
Just tell it the length and centre diameter and it generates everything else from those two measurements.

Wow. That's really cool CA.  I wonder if this would work for concrete?

Well that works quite well. With these i didn't weigh, just guessed. Still quite quick.
Oh yeah i use play doh for testing
And the clay i had has gone hard anyway.

pointy script needs a couple tweaks and I think I have to calibrate my build plate. It's been about 6 months.
But other than that, good to go  

have to admit, I was pleased.

just printing a small pointy slider.
Then I think I'll do a small sphere one (30mm anyway), just to have the whole set
Oh yeah need to add text to the things as well.


Then I'll do a little video and open up for orders

have to see about getting some clay as well. And write the text imprint script.

And print a bigger one and work out what they'll cost.

It's way faster than the press moulds and I think the result is better as well. I always found that removing the glabndes from the moulds stretched them out of shape. The rolled ones are all absolutely bang on.

Dunno why i didn't think of this years ago.  Think I'm coming up for 3 years with the 3d printer.

No point in the sphere roller. Almost as good and a lot quicker to do them by hand.
Oh and if you're making something that relies on smooth sliding - don't add protuding text to the sides
yeah, not much joined up thinking going on last night.

once i've changed the text to voids rathet than sticky out bits - think we're pretty much done. Might make the guides bit thicker in the larger moulds. But that's pretty much it
might add handles, might not.

Going to measure the clay glande uwe gave me a couple years back and make one that size tonight and see how big a roller would be for the monster glandes christian uses.

A sort of inadvertent bonus is that if you add extra clay you get a flattened glande. The motd clay the flatter it becomes, but keeps the shape. Dunno how useful that is, but it's a genuine undocumented user feature

You could also probably roll a couple at a time as i've made the roller a little longer.
