Thank you for sharing!
at least i know it's not my splicing software! the same holes are in the .Skp file
Weird, mine sliced and printed nicely on Anet A8 using Cura.

On one hand the amp draw is under 1amp, so not a lot of heat generated. BUT I was going to add 2 5mm holes in the side anyways before I print the next one. Was considering putting them at an angle so they force a little air through.Quick question... IDK the answer... you guys are making these slip-on flywheels with solid/near-solid faces. Does there need to be any cooling air flow through these motors at all? I know they pretty well loaf along in this application, and there's no prop to move air, and they generally run pretty cool out in the open air... but have you run these now nearly-enclosed motors long enough to notice the any significant warming?
Looks really good... and I love the fact your cutters are running as smoothly as they do. I'm pretty well shut down now -- moving in 8-10 days -- but really interested in what you guys are doing. Keep up the good work!

I will most likely build one with a higher kv motor in order to ramp up rpm. I am shooting for 15k rpm. New design has only 0.002" play in the mig tip, so threading the mig tip up through an old 486 heatsink (I have a bunch of these), as well as wrapping it with 14 guage copper wire. And as I said, I had planned to take the 2mins to add air holes on my next sleeve print.I went to the Emax 2215 GT series motor for the reason the David bring to our attention. I had heat problems with smaller motor. I have noted no severs heating problems using this motor. The heating problems I had was the issue with the needle guide or wire feed nozzle but when I added the heat sink that took care of the problem, Headbang brought this out in his earlier posts. Just as a suggestion; I would prefer the slip on part to be shortened. This allows the motor to "breath" and shed its heat.

As with everything I do, it could all fail.I can see where you are going here. With that 486 heat sink I would hope that it would take care of the heat problem. But having only .002" clearance in you mig tip, it would surely develop heat. I am not to sure about the air holes thing. As to what air you put in it has to be exhausted to have any effect. Maybe I am not seeing the whole picture here so forgive me if I am thinking wrong. I prefer to leave at least 1/2 to 2/3s of the motor exposed. I ask this question, how much sleeve on the motor do you need to stabilize the flywheel to the motor? The fly wheel less than the sleeve need to accommodate the bearing(s) and screw heads so not to interfere with the rotation of the needle shaft. I am very interested in your end product please keep us informed. Opinions are expressed but not required to be followed.

Ah, that I know as mine is also adapted for a specific motor. I also started from scratch (many times) and a program crashed did not help. Anyway let us know on your final. I onto a new CAD project (printed) to aid in launching my powered sailplanes. We are entering into winter here and nasty weather is already showing itself with snow in the hills. Hopefully next spring will usher in another great flying season for us. Take care.

I am using a GT2215-09 and I use ViaCad Pro. V11. I do want to note that the design I am using is a mixer of a lot of others designs. I just took what I thought to be the best ideas and recommendation and assembled into my needle cutter. I really can not take much credit for any of it.
If somebody wants to take it further have at it. I am sure it can be improved but at present it working great for me..
I see what I can do on the slots I had not thought about that. I will work on it. On the motor I cut off the shaft's extra length. Make sure you cover all the motor holes so you don't get metal parts in it then used a Dremel metal cutting wheel. Better get to it..

I edit my first post on the attachments. They are updated, I missed that error they should have been at the same plane as the wings. Thanks for bring it to my attention. Happy to hear its working for you.Thanks Keno!
Your design works great I have already cut the 3 pieces I need to make a vacuum table.
Hopefully I’m not askin too much here. Do you think you would have a minute to angle the 4 mounting slots to match the angle of the mounting wings and re-share the file?
Also what did you do with the motor shaft protruding out the back. I drilled a hole in the tool mounting plate. Maybe there was an option I missed.
Thanks again for sharing!
Looking good!! Is that a cotton ball/lube oil reservoir on the top?New cutter done and working, no issues I can see with max rpm. Next up is to mount it and cut out something!
