Little Grippy Tumblers
by BenitoSanduchi, published
Made these specifically to test Taulman 618 nylon watertightness and layer bonding. But they have useful finger grips and they look nice so I decided to share.
The regular and small tumblers get a really cool triangular tessellation pattern in stl form that looks awesome when printed. The smooth version is, uh, smoother.
About the nylon prints:
The big cup (smooth) is only 1 perimeter thick and as you can see in the pictures can be crushed without permanent damage. It is very flexible.
The small one is 3 perimeters thick and I can barely squeeze the opposing rims together. When I do, it still springs right back.

And thanks for all the designs you've put up. Â Between you and cerebus333, you have cost me a lot of filament. 8)
They list 240 here for the .35, I imagine the .5 is the same. Â http://www.lulzbot.com/Budasch... Â If it worked for you it should work for me I imagine, the setups are the same. Â I'll give it a try. Â Amazing, between this and wood filament, I can't wait to see what comes out next. Â i'm using the temp. changing color filament now and it is nice.
Interesting, where'd you find a temp rating on it? Â
I haven't noticed any changes or problems printing at 250. Â I know you want to keep PTFE below 250-260ish, so I wouldn't go any hotter. Â You won't need a fan at the tip (like with PLA) but you might want one on the heat-sink if you're worried about the temp. Â
Now that I think of it, I wonder if one could eliminate the PTFE insert and replace it with a metal sleeve of some kind. Â Nylon is so slippery you probably don't need it.
You'd have no problems printing the taulman 618 nylon with your hotend based on my experience. Â The two toughest things are 1. getting it to stick to the print bed. Â I've started printing on a PCB which leaves little nubs on the bottom of the print but keeps it from warping off the bed. Â Painters Mate Green tape works too, but the tape doesn't stay stuck when the part starts warping. Â
Â and 2. Â Making sure your idler can apply a good amount of pressure against your extruder since the nylon is so much moreÂ resilientÂ Â I crank my idler screws way down and haven't had many problems, but if you have a particularly crappy hobbed bolt you might. Â Â Â
