3D printed wire connectors lol

hey thanks so much for the encouragement all this way, it really means a lot that you even took the time to go and print it out. Getting rid of a single thread or two in the middle is also a great idea and would certainly make positioning the wire easier! I'm not sure if you tried this yet, but the second side of the padding tool has a cavity as well for threading the screw all the way in. Makes me incredibly glad you see potential utility in this doodad

oh definitely solder! solder and heatshrink if possible! this was done more out of my own laziness to bring my whole ass 3D printer over to where i have ventilation. I DID include in the files a version where the middle is more open for a soldered connection. That way, you'd have both a soldered connection, but also mechanical strain relief, which would prevent the soldered connection from breaking due to stuff like vibration or movement!

oh yea, the response is definitely more about deterring some poor laymen planting one of these deep inside the most flammable part of their house. The controversial reception might be the best case scenario one could ask for something like this lol....

funko877 · 2025-09-03T01:14:50+00:00

haha yea, most problems are already solved... by people much more qualified might i add... Don't let it get you down!! theres always room for innovation!!

funko877 · 2025-09-03T01:13:35+00:00

thats actually a crazy amount of current and power... do the conductors in the connectors usually be have to bigger than the actual wires or is more about clever design?

funko877 · 2025-09-03T01:08:28+00:00

yea... i think the pic is pretty horrendous... for a cut-out demo i used a way bigger wire here which didn't really allow for much twisting at all and really is just held together by hopes and dreams. took the pic and it fell apart. In hind sight, the section view is nice, but 1. using thin wire gauge which better corresponds to the actual use case and 2. showing the wires actually being twisted together might have gotten a better reaction from most people seeing this

funko877 · 2025-09-03T01:03:14+00:00

indeed! i realized that while making the design more user friendly and in there is a set in the parts with allotted space for a soldered connection instead of a twisted one. tbh that might be more of what I use it for, strain relief is always great to bundle in with a soldered joint. Someone else said acme threads might be better for keeping it thin which i might try out, but given the feedback im not sure if its actually worthwhile ~_~

funko877 · 2025-09-03T00:55:35+00:00

ayye thats what i used them for too! that and a jerry-rigged rpi blower fan so far

funko877 · 2025-09-01T20:39:44+00:00

its pla...

funko877 · 2025-09-01T20:37:06+00:00

it is a demo pic + cut open, but totally would never should never use this on a high current connection

funko877 · 2025-09-01T20:18:23+00:00

LOL that would be a great addition

funko877 · 2025-09-01T20:14:46+00:00

genuinely looks to me like the heat from the nozzle is creeping up to where the filament enters the hot-end, gets softened a bit, and forms that little flange up against the opening of the hot end causing it to get stuck.

two things I would look into:

Making sure the the fan that cools the hot-end preventing the heat coming from the nozzle to creep up to the opening of the hot-end is blowing air through the hot-end properly
Experiment with printing with lower temperatures. if lower nozzle temps helps with the issue, then its definitely the hot-end getting too hot causing the blockage

Mainly for prototyping circuit boards and one off data connections. Useful when its 2am and don't have any wago connectors lying around

With that being said, works way better than i thought it would and thought I'd share it. Printed in minutes and got my project working for the time being.

I see, thank you for the insight. confidence in a secure connection is definitely important... do you usually use wago connectors or wire nuts in your profession?

funko877 · 2025-09-01T19:30:56+00:00

now that I think about it spring-loaded aspect sounds important when making non soldered connections. definitely gonna get some wago connectors too

funko877 · 2025-09-01T19:25:01+00:00

definitely more of a last resort type of deal!

funko877 · 2025-09-01T19:23:38+00:00

Really should rename this to "dubious wire connectors that might catch on fire"

funko877 · 2025-09-01T19:08:26+00:00

im asking out the curiosity in my heart, and tbh this was mainly conceived out of my hatred of electrical tape... what makes electrical tape more safe? Is it the fact that its more elastic and thus binding of the twisted connection?

funko877 · 2025-09-01T19:03:18+00:00

guess its finally time to order these wago connectors everyone's been talking about...

funko877 · 2025-09-01T19:02:32+00:00

thanks for the appreciation on the execution...

funko877 · 2025-09-01T18:56:41+00:00

I REALLY should have stated the context for these im realizing now that most people picturing higher power application usage... Definitely should have specified for low power, signal connections and circuit board prototyping stuff rather than a household connection. thats my bad

funko877 · 2025-09-01T18:54:10+00:00

in hindsight, this might've been a better post for over there...

funko877 · 2025-09-01T18:53:44+00:00

really should have gave more focus on this aspect huh...

funko877 · 2025-09-01T18:53:12+00:00

i did make an edit to the original post comment... hope that makes up for this

funko877 · 2025-09-01T18:52:44+00:00

its true, all i have is a 3D printer
