How long does it take to print one of these out?Last one of this design I’ll show, im fairly pleased with it for now. On to the next thing.

a little less than 3 hours. I could probably get it down some more but since I’m using PLA I’m leaving it bulkyHow long does it take to print one of these out?
Anyone have a link to the little knob that slides over the quicklink nut to give you some purchase of it gets locked down to tight. I think genesis used to sell one but they don’t have it on the site anymore.
Give me the size of the hex flat to flat and I will be happy to model you one and send you the stlAnyone have a link to the little knob that slides over the quicklink nut to give you some purchase of it gets locked down to tight.

I was having issues with it seizing up after rappel, I threw some super Lube on the threads and that solved it. Silicone with Teflon, no detectable smell(to me). Home Depot / Lowe’s has it. I use that stuff on everything. Probably a dry lube with teflon would work too but I didn’t try it. I could sketch up a part pretty quick but personally I’d hate one more thing to carry or have rattling around(and leaving it in place seems like an added risk).Anyone have a link to the little knob that slides over the quicklink nut to give you some purchase of it gets locked down to tight.

I’ll get that over to you tonight if I get a moment. Thanks a lot.Give me the size of the hex flat to flat and I will be happy to model you one and send you the stl
Are you willing to share the STLs for these? I would love to have print some upI didn’t have a wing nut to try so I printed this two sided knob instead. It needs a decent amount of torque since it is a friction held arm. The knob made it very easy to set. I used a couple layers of duct tape as the washer. It’s holding nice.View attachment 104215View attachment 104216View attachment 104217View attachment 104218
I’m thinking underextrusion since it’s brand new filament, just opened the vacuum seal. No popping.. I’m going to play with settings some more and go from there. Higher temp to help extrusion or no? I’m also running no bed fan? Print speed is super slow 13-15mm/s. Retraction 1.5-2.Usually with TPU I get a lot of stringing and takes a while to get retraction down. Could be the filament got wet? Usually that will cause blobs like that when the moisture boils off. Does it make a popping sound when it’s printing? That’s the easiest to fix, just dry it at 50C or so for however many hours, I’d say 4-6.
Otherwise it might be underextrusion, which is a little more involved. Those are my best guesses.
It’s Bambu lab HF 95A TPU. It’s just what was avaialble at my local store. My coworker ran the 75D poly maker and it looks great.What TPU is it? I've noticed a lot of variation in required settings for 95A TPU. I've settled on only Polymaker or ninjatek. Minimal lot to lot variation.
95A TPU likes to be dry and run slow. (75D can almost be run like PETG)
If you think you are having extrusion issues, swap in a new nozzle and run a calibration print and go from there depending on how it measures.
I run a bunch of the polymaker at work (tool covers for 40 cnc machines so folks don't accidentally cut themselves on sharp tooling) at 210/30 and 30mm/s. My retraction is 1.0mm at 25mm/s.
I’d give 2:1 odds it’s moisture, I don’t print with TPU often but when I moved away from PLA I found most materials need to be dried before first use. With nylon I dry for a few hours and print directly from the dryer, and keep the dryer running until I use up the roll or vacuum seal it back up.It’s Bambu lab HF 95A TPU.

The tool head covers is a great use for this.
When I free extrude it looks fine but when I go to print it looks bubbly. I may go ahead and have my coworker bake the moisture out of this brand new roll.
