sorry folks -been tinkering with the file.
Settings are now as good as I can get them for hinge placement.
Last three have no discernible gaps once assembled.
40mm skull mould is available for ordering.
At some point I'll work out why I can't resize it without things going all to hell - actually, the last tweak I made to the glande mould about 10 mins ago - could be the culprit - we'll see.
But for me it's the ideal size anyway
I might make it in 30 and 50mm.
Any smaller or larger would seem daft.
Although a 20-25mm one would make great sling shot/catapult ammo

Given that the metal hinges are 40mm wide - smaller moulds will look pretty strange anyway.
I could spend a bunch of time fiddling around and maybe save a few grams - but Honestly, who cares lol
The first test mould (50x30) is now out in the wild and I will be hassling cairo till he makes a bunch of glandes and sends me pictures

Vetryan - your's will start printing overnight.
Going to be a 60x30

The body of the moulds are made from PLA (polylactic acid) this is an enviromentally friendly bioplastic. Made from renewable vegetable matter - cornstarch mainly.
While strong and durable it is also biodegradable - in the right conditions: IE: a hot compost heap.
Hinges and bolts are made from stainless steel.
No petrochemicals used.
Moulds are washable, but not necessarily 100% watertight.
So drain well after washing.
I'll get pics and usage video up as soon as cairo's given it a thorough testing.
I never managed to break the original printed hinges - so I need someone a bit more heavy handed to do the thorough testing
Short of the actual mould breaking - and I'm printing these with settings that take a lot longer than my usual settings and are a lot stronger - I don't foresee any issues.
But, unforeseen issues apart - they are ready to be released into the wild

I'll sort pricing out shortly.
