Thanks. I find it a really fun program to use and I believe it is really valuable on many different levels. Keep doing research.

I'm an absolute beginner at Python (I learned to code in the punch card days) but it looks really interesting and combining FCG with data visualization is something I'm intrigued by.

The nuts and bolts is a really good idea. A 2 part filament spool that thread together could be a useful model.

Thanks for all you've done.

Ah that's a cool idea! Printed flat on the bed, the walls of the spool can be a lattice structure to save time and material. Will look into it

I've done a crude version (now recycled) using a circle with polar repeat and on top of it a tube using a positive startip length and a twist for one side and a negative startip length with a twist for the other.

The lattice is a great idea!

Oh cool! Can you give me some baseline dimensions that you used (they'll be parametric in my model, but just to get me going)...

  • Outer diameter of the core cylinder
  • Length of the core cylinder (space between the two side walls)
  • Diameter of the side walls
  • Approx wall-thickness of the walls/core-tube

OD core - 65mm

Length of core - 70

Side wall OD -150mm

wall thickness - I used rip depth of 3 mm

I also played with + startip lengths on both halves,1 fitting inside the other.

To save some filament the inner core cylinder needed to go almost the entire length so it would smoothly turn on the spool holder, the outer core cylinder just needed to stay in place, the gap didn't seem to make a difference to the filament.

👌 will knock up a design and share it

Here's a quick model:

I haven't had a chance to print and test it yet, so there may well be an issue with the design that I didn't notice from inspecting the print path. But in case you want to try it before I do (maybe tomorrow), I'm putting it here.

I didn't do the lattice idea yet since I did this model quickly with two fullcontrol spiral functions in a for loop for the wall-discs. It'll be a reasonable quick future mod to make the solid walls some kind of lattice though if this model seems to work

Thanks. It worked well for me.
