Hi Michael, hard to tell from the pics.
try printing:
Sphere_int_H25.stl
Sphere_D42.stl
I loaded a couple of photos under 'I Made One'
Hi Michael, this was designed to be loose fit and it should be really easy to assemble.
Could you post a photo of your print?

Hi. Any chance of separating the parts on this? I live in a cold climate and the screw part keeps lifting :)

Hi Mxdbag,
try to print:
Sphere D42.stl and Sphere int H25.stl
why not just smudge the first layer

Hi Mxdbag,
I'll separate them and also add ear rafts.
Will have to do it when I'm back at home later tonight.
this ended up being a torture test for my printer, after countless failures i was able to get a complete print. it kept skipping steps until i lowered my stepper motor current and decreased the acceleration. printed nicely.
because it breaks evey once and a while
make a version with only the screw
try to print:
Sphere D42.stl and Sphere int H25.stl
Ok... whats the secret??? So many thing/kits here on the Thingiverse yet so few get the fit this thing gets. Parts screw together PERFECT! How'd ya do it??? Why can't more be THIS good?
Thanks Andychn!
the secret is to try and try again until you get it right :)
That's what Rapid Prototyping is for right?
My first few prototypes did not even fit properly. For designers who want to design male/female threads, model a CAD design of the male and female thread on a small size first and print them out. If it fits, use the design on the actual final design and print it out. Saves time and material. I learnt it the hard way hehe ;)
Unlike others, my print was too tight to fit, it screwed in a little but then binds, a bit of back&forth and it gets 1/2 way in.

Presumably over extruding?

I was trying to work around the overhang, looks like he found the solution using chambers :)
Actually designed this as a little exercise to print a sphere without supports and without the use of adhesive. Cheers! :)
This is a great little design. good stuff!
Thanks :)
