I enjoy Pokemon and wanted to try a "flexi" model. Weedle is a classic and allows for me to try making a flexi-model.
As of 7/13/23 the “Weedle v4” has the best results, though it doesn't wiggle as much as I wanted (but it can be printed flat and then bent for display with some support).
I used ring connections and the model is small, so I suggest scaling it up by at least 400% (probably better to do 500%, I tried printing at 275% scale and the joints did not come out well).
I added an updated version (v2) in which I shifted the different segments to lay directly on the printing surface. As the model has overhanging areas it will require supports. The model is small (only 7.99 x 33.262 x 9.687 mm) in size so scale up when printing; without any scaling the model will print in 19 minutes (according to Cura Slicer), but I suggest scaling up.
If someone finds settings for the model that work message me / comment with the details so I can update the post (will acknowledge). This will be an ongoing endeavor for me, as it is my first “flexi” and I want to make it work.
*Update 6/21/23: I printed version 2 at 375% scale and it was better than my first attempt, but it wasn't great. I feel 375% to 400% scale is the minimum for printing; I'm next going to try changing joints to improve (not sure when I'll be able to)
*Update 6/22/23: I designed a third version (file “flexi weedle v3”) that is scaled 400% from the original version and changed the joints to a thicker / beefier version. This version is 133.09x31.98x38.75 mm in size.
*Update 7/1/23: I made a fourth version ("weedle v4") that is scaled 450% from the original version and changed the type of joint (no longer rings, see image of red joint for example). I made the first 3 images of the fourth version, and the rest are of the original one.
