3d printed a smaller pulley

Recommended Posts

I got a Juki lu-563 and as soon as i got it i took the old clutch motor out and now i use it as a boat anchor ;)
I invested in a Jack JK-563A-1 servo motor and its nice ! However ! its abit to fast for me even at its slower speed and when i did some digging around i found that i wasn't the only one with that problem and tried to find a good solution for it without spending 2-300 euros on top of that and i figured a smaller pulley would do the trick but couldn't find any 40 mm pully for it.
After some brainstorming i figured I just make a 3d model of what i needed and hired a 3d printer owner to print it for me :) and it arrived today, i needed to drill out the hole and do some file work to get it to fit and now it installed.
I printed it in PLA as a test and gonna run in until it falls apart but im 
surprised that it works so well !
im totally happy with the speed now, i can do a recording if anyone wanna see the speed.

Here is a few photos

That is some 'solid' MacGyver'ing right there . I giving you a Big thumbs-up on that print pulley . I seen it done ( printed pulley ) on ( the Larger Pulley ) with a under the table  gear reduction and the guy swears it works perfect . What material you printing with ?  The material will probable work for long time if you keep the friction/heat down with turning a low RPM .

I see in your forum profile you from Sweden . So I don't know if you get the old 80's 'MacGyver' episode reruns there for the DIY reference  ....LOL

Thanks ! 
i was around for the original run of MacGyver !
Printed it in PLA as test, see how it holds up, where not sure it would work at all and my backup plan was to do a speed reducer with a large and small pulley.

If you search on ebay for "45mm pulley" they're around $3-4.

Nylon may be a better long term filament as stronger and often used in gears etc, now he has the STL file made for the printer just a few hours printing to use another filament

$3-4 shipped from China. Just ordered one yesterday. But I guess it's part of fun to DIY :) I do lot's of things that don't make any financial sense..

I did find alot of 40-45 mm pulley but none that fit my 13 mm axel that my Jack have and i guess i could have spent more time to trying to find the right one but in the spirit of DIY whats the fun in that ? :) i learned 2 new skills and hopefully inspiring someone in the process.
I keep you posted on the progress.

Slowest i could run on the slowest speed (500)
The knocking sound is the hook hitting the needle, i just switched my hook (B1830-563-BA0) to get thicker thread at the bottom and i need to adjust the distance from hook to needle. sorting it out tomorrow.

Thanks Stor, that looks good and slow. I have had this on my list for a while now also, maybe get around to doing it one day. the jack is also a little too fast for me. :spoton:

No worries !
Maby one of the guys above can point you in the direction of a seller if you dont wanna go thru the pain of 3d printing one, but if you do wanna 3d print one let me know and ill send you the file.
