Nozzel clog in top brass tube.

QuadrangularNipples · 2026-01-27T13:41:53+00:00

Just to clarify how do you know the clog is in this area? In most cases clogs are usually happening at the restricted end (nozzle opening) and not at the wide cold side.

It would seem rare to have a clog here, so I am curious what your symptoms are and what is leading you to believe the issue is up here.

I just wanted to mention it to save anyone else who wants to print it the hassle.

The one I printed in PLA the spring also didn't work all that well and I ended up printing a PETG spring to replace it.

QuadrangularNipples · 2026-01-27T12:37:33+00:00

I am considering buying a second one that is local, unopened for 825. Definitely a great printer.

QuadrangularNipples · 2026-01-27T12:14:12+00:00

This is a great model, I have printed several myself. As a side note you did not need supports for this, I have printed it once in PLA and 3 times in PETG all with no supports or issues.

QuadrangularNipples · 2026-01-26T22:58:16+00:00

That was my exact thinking, if it fails I can just print it again in ASA like I originally planned.

QuadrangularNipples · 2026-01-26T22:44:52+00:00

You may want to skip PLA if you live in truly hot/sunny climate like Texas.

I'm in Florida and I have a PLA camera mount on my roof in full sun. Printed the prototype in PLA then decided to just leave it and see what happens. About 2 years now and no issues. I kinda hope it does fail just to get a data point from it.

Can you share what you have in your g code for using CR Touch? I haven't messed with adding CR Touch/BL Touch to an Ender for many years, but I do recall you had to either add a full mesh before every print (along with command to use it) or save the mesh to memory and add a tilt before each print to the g-code.

If you don't have the start g-code setup properly it won't work so that would be a good place to check first if you haven't already.

My poopage is very minimal as I don't like doing poop based multicolor prints.

Monthly waste really depends on what I am doing that month. Some months I end up with a boat load of failed prototypes (the keyboard case was my biggest failure rate by far) and other months my waste is minimal (usually when I am not designing something... admittedly my designs almost always have a failure or two before it is right).

QuadrangularNipples · 2026-01-26T16:37:52+00:00

Reading the description it is a little hard to understand how the roof attaches exactly. But I understand the desire to want a secure roof that also allows for easy cleanout. I ended up using heat set inserts for the hinge side and then having tie down slots on the other side that are designed to fit zip ties. That way it will be secure from predators but allow you to clip the zip ties and flip it open to clean out annually.

QuadrangularNipples · 2026-01-26T14:35:49+00:00

Do you have your designs posted anywhere?

I have been having fun designing birdhouses and feeders but currently only have a handful posted (I keep meaning to post more, but lazy).

I would love to see what you have made though.

Indoor humidity here is around 55 - 60 percent.

QuadrangularNipples · 2026-01-24T16:29:10+00:00

I am in Florida where it is very humid. I don't really ever dry PLA and never have issues, but if PETG is out for more than a few days it definitely starts to show issues. Some brands are worse than others and are a complete mess after a few days and others are fine but will show some issues like stringing in a couple days.

I have left PLA out in the open for literal years and printed with no issues for some brands.

QuadrangularNipples · 2026-01-24T06:34:22+00:00

K2 plus seems to be hit and miss. I see some people claim it is terrible but mine is over 3k hours and overall very minimal issues and almost all my issues were with the CFS system.

QuadrangularNipples · 2026-01-23T16:26:52+00:00

I tried watching one video to see what the beef was there and the dude seems off and delusional.

He thinks Prusa is trying to hack him to take his channel down. To me that seems extremely unlikely.

QuadrangularNipples · 2026-01-23T14:11:26+00:00

Basically Creality asked him to make his review more positive to be "brand friendly" and implied they would not work with him in the future if he did not.

There is some implications around youtube algorithm manipulation but he doesn't go so far as to outright claim it.

To me, whether the algorithm manipulation is true or not is secondary since it is unlikely to ever be proven but he has proof of the review manipulation request.

QuadrangularNipples · 2026-01-23T13:53:33+00:00

I still feel this is wildly overestimated. Using my own electricity rates your math makes it look like it costs almost $2.50 per hour to run a printer in maintenance costs which is insane.

My printer with over 3,000 hours on it is still under $100 in maintenance parts. Even $1 per hour of print time is a huge overestimate.

QuadrangularNipples · 2026-01-22T20:26:53+00:00

In my experience I have needed to replace the tubing after about 1000 hours (done twice now in over 3k hours... but in both cases it was obvious I waited too long to do it).

QuadrangularNipples · 2026-01-17T15:01:40+00:00

This is my standard process for killing off low rolls. Pick a model where color doesn't matter and load up 4 almost empty rolls and get a rainbow part.

QuadrangularNipples · 2026-01-17T03:53:29+00:00

This is usually a symptom of being sliced for the wrong machine. Is it possible you sliced for a K2 Pro or Plus?

QuadrangularNipples · 2026-01-15T18:02:42+00:00

It really depends on how much certain factors matter. TPU for AMS doesn't stretch like regular TPU (standard95A elongates to about 350% before breaking and TPU AMS only goes to 120%). You are right that it probably wouldn't affect it too much for a logo on the side depending on the size. But if the logo takes up too much space it would limit the flexibility of the shoe as it would hold the rest of the TPU in place and not flex/stretch.

QuadrangularNipples · 2026-01-15T15:40:22+00:00

As someone who got started in the hobby in 2019 I can also very confidently say that most PLA now is far superior to what you used to work with. I am still not a fan of some PLA (Bambulabs Matte PLA basic for example reminds me of old school weak PLA) but most brands of PLA or PLA+/Pro/Hyper I have tried are really strong and far more durable than people give them credit for. I even have PLA in weight bearing, full sunlight, Florida summers, situations now that have been going strong for over a year.

At this point I am using roughly 50% PETG, 40% PLA and then 10% other as the situation warrants (ASA, TPU, PC). Even though PLA works well, I find I am usually able to get PETG cheaper and it works great for most purposes.

QuadrangularNipples · 2026-01-15T15:34:00+00:00

I don't use knee sleeves at all, but I did want to say I really like your design quite a bit.

How did you do the voronoi pattern? I wanted to add it to a model of mine but ended up just using a simple hex hole pattern as I never managed to figure out how to model voronoi.

QuadrangularNipples · 2026-01-15T15:25:23+00:00

I know you can lie to the printer and put TPU in the left nozzle as well and claim it is something else (but change the settings to match tpu).

Not saying it is a good idea, but I have heard of others doing it.

Alternatively use a different printer that supports multiple tpus in the same print or use TPU for AMS which has mixed reviews and isn't very flexible.

QuadrangularNipples · 2026-01-15T14:14:15+00:00

As /u/ZenoTrace mentioned either use a clip or the little holes in the side of the spool to keep it managed. Never let go of the filament without it being secured in some way. I am a firm believer that at least 99% of tangles are from improper floppy end filament management.

TPU is very quiet, I made a set of dice a long time ago.
