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.
I'm just doing a large model and the usual joints don't have enough tension to stand.
I've tried a couple of pin designs first but haven't hit on a working design. I'm thinking
a ball joint with a tighten-able socket (via a small set screw). Like an armature they use
Thanks for your thoughts and help. Much appreciated.
Sorry to report that I don't accept commissions for the 3D modeling and printing stuff.
I wish you luck on this. It seems exciting. Wish I was talented enough and had enough spare cash lying around to try something like this...
i like how you smoothed them out with acetone to get rid of that jaggedness.
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)
cool you gonna paint them?
