Rainy day project, new wind spinner mount. Not having much CAD experience I tend to mess around until something looks plausible then do a test print. 1st issue: mount is too big for printer. No problem, slicer will cut and make connectors. Still a problem: I can't glue worth beans, dowel connector isn’t strong enough, and 3 metal pipes stress the joint. Maybe I can reduce radius enough to print without cuts? I didn't anticipate all of the twisting pipes would have even with two mounts. Seems like pipe slots should have set screws, or what if they were split and then clamped onto pipe with screw, hose clamp, or tie wrap? Hmm…
I have an idea in my head to CNC a “better” pen, and pencil for myself.
However, after poking at the idea of a better pencil, I think a squishy #3DPrinting TPU sheath around the barrel may be a perfectly decent solution… for the pencil. I’m still making a better pen. ;)
the little double-chamfered bit on the end of the cylinder was slightly bigger than the hole, BUT the TPU was just flexy enough to let me shove it through, and then have it expand and hold it snugly in place.
🧵 using sine-waves to avoid stair-step layer lines continued:
Attempting to avoid the stair-step at the bottom of the pen holder in @noted I took the sine-wave, and revolved it into a cylinder, then subtracted it.
Then i used the "loft" feature to blend from wibbly in the pen holder to flat at the top
The result is fascinating.
This GIF only hints at how it moves in the light & this is with the most matte filament I own.
