We have a sub-forum dedicated to 3D printers and Laser cutters where members share files they've created for them.

Ok wiz, I will stick my next stl there.

I've received the JK 563 couple of days ago but I did not have any pulley removal tools so it took a day to get the right jaw puller... Anyway I've tried my 3d printed pulley today which unfortunately was very tight on installation and cracked.... so tomorrow another print. Thanks Jimi for the stl, but I will try the one I made in Fusion 360 first. I can share my Cura settings for support if you have problems with support being difficult to remove after print.

I've also received a standard straight bore 15mm pulley as Constabulary suggested just to see how easy is to modify it for the JK. Installing 1mm sleeve sounds like a good idea but whats about the bigger 5mm key hole in the standard pulley instead of 4mm on JK ? 

Matt, it took an hour to have one half printed. It would be much quicker in PLA but making it in PETG and 0.1mm layer height took longer..

I've got Anycubic i3 Mega S which I modified a lot.... Its relatively good and not expensive starting platform but has few issues in my opinion so has to be modified sooner or later otherwise results are inconsistent. If you need something good from the box then Pusa i3 mk3 would be your choice.

I can't wait to see what he can make with the new printer and a full report.

Me too, but it will have to be in the 3D printer and laser section. Just waiting on a few more mod parts to come in and we will see how it goes.

I would love to see another of your write ups about this New Bigger printer and some nice samples. 

I might need to change my direction in hobbies or sell something, can't afford another hobby.

 Hi 8dsf, i printed the 50mm one yesterday with support to see how it was, and the support came off good and the pulley just slipped on no problems??? Cannot understand why it was so tight?? i printed this at 2.5 layer height, PETG, no bed heat and standing upright...

Might be time to do a 20mm cube and cylinder test to check how true the measurements come out??? I know if you up the flow rate as I do with my 1.75mm filament where I change that to 1.74 caus I like the tight layering does make the prints come out a little over size. Sometimes that means we draw to allow for these changes and the file sharing is not important at the time. A simple scale increase or decrease in Curra should be an easy fix though.

That took 1h54 i think it was to do? The first one there in my hand is still working no problems, i just printed the other one to make sure i was not sending a dud file for 8dsf. I don´t remember changing any flow settings, and last time the cube was 20x20x20.1 or 2.

Thanks Jimi.

I have printed today the one piece pulley and I agree removing the support was  bit challenging but it came off eventually :).  The one thing I dont like is the small runout when the pulley is attached, its not bad but its not perfect .... I have not measured it yet but I will do it tomorrow just to my records. I am gonna print two halves tomorrow from your file and compare. Have you noticed any runout on your 3d printed pulley ?
