HOLY poo poo YOU GUYS IT WORKED I measured it out and made a model, meshed, sliced, and printed it and everything miraculously fit the first time. The screw hole was just right. Thanks, Sagebrush, your advice was spot on! Here's what it looks like when it's put in the right side up and connected to the hinge. https://i.imgur.com/nGZ0n7N.mp4 I've had this g-dang desk for 8 years and I broke the hinge on the first day by screwing the bracket in upside down. Since then I've tried holding the door together with duct tape and I even looked on the Ikea website for replacement parts (and was stonewalled by their customer service). Now it finally swings properly and doesn't catch on the bottom edge. Let's hope this one lasts a long time. This is the most useful thing I've done in six months. I'm blown away at how well it works. I'm gonna go around the house and 3d print all kinds of unnecessary poo poo Also I tried printing the legos again after cleaning the sheet. I think the adhesion was slightly better because the curling wasn't as bad, but it was still enough to cause the pieces to detach early. I made the bottom of the bracket completely filled in, hoping that it wouldn't come off the sheet but as you can see in these pictures it still did. I'd rather not use the gluestick so I ordered a smooth sheet and it should be here in a week or so.

A brim can help with edge adhesion in the meantime.

And if it breaks again, who cares because you still have the file and will until the end of time and can just print another one in half an hour!

I was pretty excited when I designed replacement stakes for my low voltage landscape lighting. The originals were made out of some sort of plastic that just fell apart after a year or so in the ground. I couldn't find anywhere to buy them, and such things are not standardized. So I set down with calipers, my last remaining original stake, and Fusion 360. After watching some basic tutorial videos I was able to recreate the stakes and even improve the design (at least IMHO). I also modified the design to be able to print easily without supports. The PLA+ printed stakes have already lasted longer in the ground than the originals. All 16 of my lights are using my printed replacements.

I mean, I got a pretty well sorted printer, but first hint of adhesion problems, I'm smearing that gluestick on and then address the underlying issue once I have lull in printing.

That success post made me think that I should design a chain guard for my bike asap. Only a matter of time before I ruin my trousers. Brims solved all adhesion issues on small parts in PLA for me. TPU is the only one that likes to "curl" it seems, but that was a for a big box thing. The octopus I printed came out near perfect.

Gluestick washes off near instantly with hot water and soap. It's the easiest and simplest solution and will not harm your print surface one bit.

Hell I don't even use soap and water... This: https://www.amazon.com/Sprayway-Glass-Cleaner-15-Ounce/dp/B07K1ZD36P Works great for cleaning off Elmers gluestick. I keep it and a roll of paper towels by the printer at all times. But I am a bit "old fashioned" in a way, as I still print on glass, not any of these new fangled print surfaces.

What's the best upgrade path for the ender 3 buoldplate of I want to do Petg? Right now I have the heated glass bed, but obviously printing on that directly is a bad move. Do I get a buildtak flexible sheet or something like that?

w00tmonger posted:What's the best upgrade path for the ender 3 buoldplate of I want to do Petg? I'm not sure what the best is for petg, but I've had good luck with regular flat glass and a lot of glue stick. PETG can be kind of a pain in the rear end but a thicker than normal spread of glue seems to help it stick and stay but also release later. I have also read that blue painter's tape is good for PETG but haven't tried it myself. Matterhackers suggests those as well as PEI or even buildtak: https://www.matterhackers.com/news/how-to-succeed-when-printing-with-petg-filament#D1

The Eyes Have It posted:Instant, but messy I also used to be recalcitrant about using glue. I considered it messy and had the attitude that well the printer should work without it so I will continue to stubbornly try to make it work. Later I got totally sick of messing with the machines and having prints fail so now I just put glue down any time I'm concerned about the print geometry or anything. With the magnetic build plates it's trivial to wash the glue off if you need to. It's water-soluble. Cory Parsnipson posted:Oh. Hmmm. How often are you supposed to reapply it? Sometimes taking a print off the bed will peel the glue away with it. You can touch up those spots with the glue stick before the next print. If I were using glue for every print, I'd reapply it when it quit working or when it started to look scummy. Maybe every 10 jobs or so. PEI + PLA + glue provides more adhesion than a bare bed. The glue acts as a glue to keep the part stuck. PEI + PETG + glue provides less adhesion than a bare bed. The glue acts as a separation layer to prevent the print from bonding too strongly. You decide whether you need to use the glue in either situation based on the amount of adhesion you're getting.

Petition to have someone design a gluestick head for the prusa XL tool changer when that comes out, and custom gcode that applies it only on the bed where the print will be. Knocked out some washer/spacers for a free IKEA armchair my wife picked up, drew them in tinkercad, sliced and printed during a conference call. I love living in the future sometimes.

What is the stock surface that comes with an Ender 3, incidentally? Is it PEI? Smooth or textured?

Sagebrush posted:What is the stock surface that comes with an Ender 3, incidentally? Is it PEI? Smooth or textured? It depends what version you get. My basic Ender 3 had a kind of thick soft buildtak surface that was a bit weird. It was soft enough that it would pull up on corners and I'd get warped prints due to the surface lifting up off the bed since the binder clips weren't enough. I'm not sure if they come with that now on any model, but I believe the Ender 3 v2 has the creality textured glass surface which has some stuff on it (supposedly Carborundum which is silicon carbide) that holds PLA down well as long as it's clean. I bought that for mine and liked it so much I got the CR-10 sized one for my Sunlu S8 as well. The Ender 3 Pro has a magnetic sheet but I haven't used it myself. The surface looks like its textured.

The big thing is that you're really going to regret it if you do a long print and have it pop loose or warp at hour twenty or something. I never have adhesion issues and I still smear glue all over my bed for any print that's longer than a few hours. It's just not worth the pain.

I just used BedWeld for the first time after many many many spools of ABS over the past few years. I've been trying to really keep the edges flat, and aside from the normal temperature tuning in my enclosure I've also done dozens and dozens of test prints with aquanet or abs slurry on glass but nothing was perfect. Last night I printed a big heavy abs print that failed every previous attempt to stay flat with bedweld for the first time and it is insanely perfectly flat at every corner, and released itself from the bed once cool.

Can anyone with a Prusa (this is an MK2) tell me if the sort of knocking sound it's making in this clip is normal? I'm getting what seems to be some under-extrusion, but if I slow it down it goes away so wondering if the extruder is having trouble keeping up? https://photos.app.goo.gl/eRZXoNdQZj3Him5FA

Yeah, that sounds like the extruder skipping steps to me. Lightly grab the filament close to the inlet while it's printing, or rest a finger on the extruder body, and you'll probably be able to feel the clicks. That happens because, in order of likelihood: - the extrusion temperature is set wrong (or the wrong material is loaded) - the nozzle is partly clogged - the thermistor is broken - the extruder stepper driver is overheating - the extruder motor or heater block are broken. Double check all the temperatures and then consider replacing the nozzle, imo.

You can also get clogs if the nozzle is too low but not so low that it impacts. That means the filament can back up over time and start causing the clicking.
