In theory the 8 way ratchet seemed like a good idea, but ultimately I discovered that a simple pin worked much better. I wasted a lot of time trying to develop the ratcheted joint and I got something decent, but it had limited posing options and it was not as durable as I had hoped. I now use simple 5mm pins. the female socket starts as 5mm, but i need to adjust it depending on the material I'm printing with... tolerances for ABS can vary somewhat depending on manufacturer and color additives. I smooth my parts with acetone so that effects the way I handle the parts. I test fit all of the pins/parts before I smooth them with acetone. Then, I wait a full 48 hours after acetoning before I assemble the parts. This give the chemical reaction enough time to fully stabilize. If you start assembling the parts too soon then the plastic is still a little soft and it will ruin the joint tension. Hope this helps.
There are a lot of choices for entry level 3D printers now. Here's a link to the one I use. It's not the cheapest nor is it the most expensive. BUT it is very reliable and seems to work a lot better than many of the others. Afinia 3D printer ----> www.afinia.com/3d-printers
I was going to send a search party as nothing had been posted for awhile. I figured you were working on something cool and you did not disappoint! A friend of mine wants to go in on a 3d printed. I need to get into this soon.
Good to hear. Any concepts on selling at some point? I can't say I would ever buy one (though it would be tempting, but I'm often broke), but I'm sure it could sell well. Even if it is not assembled pieces that need to be put together like a model kit. Some of us would actually like it better that way...
Hi Bill. I sold the first couple I made and I'll be selling some of those Mechanauts. These mechs take too long to make for it to be practical to sell them. I actually sold these to friends at a show but now I don't have any for myself I have all the parts printed for a new set but I haven't had time to clean them up (that's the hard part)
