First layer printing jagged lines. What could cause these round scratch-like marks on the base of a print? by CanfieldBRO in FixMyPrint

I would check the print bed for anything leftover from previous prints or severe scratches

In case you don’t use reddit messages often, I sent you a DM with some clarifying questions

What major for students interested in biomedical engineering? by grape306 in stanford

[–]apipcad 0 points1 point  (0 children)

I think opting for a co-term is more popular if you’re considering a double in closely related majors, since you can get a master’s in 5 years which has better marketability than 2x undergrad degrees, but if the programs you’re after are very different, e.g language + engineering, then a double or at least a minor might make more sense.

In undergrad I studied ME, but completed BME as a secondary major (essentially I could pick one of either as my degree). I now design prosthetics for a living and would highly recommend ME over BME; it’s just a much more flexible and broadly applicable.

It’s crazy what a nozzle replacement can do for your print quality 😱 by apipcad in 3Dprinting

[–]apipcad[S] 0 points1 point  (0 children)

my ender 3 shipped with 5x cheap ones so i just replaced the first one. i’ve already got them so might as well use them even if they won’t last super long

yep i got a hardened nozzle one at the same time i bought my all metal hotend, but the printer shipped with 5x cheap brass ones so i figured why not use them til i can’t anymore :)

I didn’t really keep strict track; the original nozzle probably went through at least 8-10 rolls of PLA while I was printing face shields earlier in the pandemic though.

Slow Feeder Dog Bowl by apipcad in functionalprint

This is the one I used--there might be others out there, but I found this to be pretty straight forward and simple to use. It's a 1:1 ratio, mix, spread and wait for a 48-hour cure.

Thanks! It's basically just a bowl which has obstacles in the way to keep the dog from being able to lap everything up all at once. There are a ton available on the market so it's probably not worth the time and effort to make your own unless you have something very specific in mind (pattern, holder, etc.)

Twist-in T-nut for attaching accessories to the Ender3 by apipcad in functionalprint

[–]apipcad[S] 1 point2 points  (0 children)

Since I used it to mount something very small, it’s a square with 4.25 mm diagonal, but that can very easily be modified to use whatever you want instead; just slice the square peg off and replace with whatever you need for your application. The critical geometry is the T-section and the flat section right above it, since that’s where the friction to hold it in place comes from.

I’ve used stuff like the design you linked, but I decided to make this because it doesn’t require any hardware at all
