Put it back on right now or I will tell everyone you have an unlimited amount of bog roll !
Honest it does help a LOT and also keeps fine dust out of the motor too.
Mine tend to run lukewarm even at higher speeds
Oh and BTW there are 3D plans online for a slightly more potent fan for these things but while you are sat on your throne you can look it up...
Not like you are busy or anything
Well, I was sitting here staring off into space (as required by the conditions set forth in my Corona Virus House Arrest). And it occurred to me that a not very well thought out box I had printed for a different project might have a use after all.
It fits pretty darn well. I just have to design and print a lid for it for the knob and the other switches/buttons.
LOL
I suspected you were entangled in the 3d but that's a real bonus right there
Until even the local post start to handle packages I am subject to plywood, nails, and glue still.
So still sorta stone-age here but given my old fart status I am good with that.

You'll get "entangled" too. It's pretty incredible what 3D printing technology can do. And for a $200 printer! You'll start seeing all kinds of things you can fix around the house (Just one oddball example: Clock hands for an old clock my mother kept for no good reason). Or make those things better. Make project boxes the way you want them. Tools, like a circuit board holder for when your soldering.
I just printed one of those fans you mentioned on Thingiverse. Printed some T-nuts last night. Yesterday I designed a clamping system for the CNC to hold PCBs while I mill them out. Every day, I think of something else to draw up in DesignSpark Mechanical and throw on the printer.
And the designing part is what I like most. I'll find a need and go look at stuff on Thingiverse for inspiration. Then make my own design.
It really is addicting. LOL
I know !
So many designs just sat in limbo right now...
May bite the bullet when the money comes and just "go ALL IN" ! (she said)
A clamp I'm working on (saw similar in a video a few days ago). Doesn't quite work with the way I have my waste board set up. But if I remove it for some reason, something like this could come in handy. Have to place it in the "maybe" pile.
So how are the "ADULT TOYS" coming along ?
Not sure about that devastator 3000 ultra you showed me.
I mean that thing would need half the power grid.
Where you been? I'm all the way up to the Devastator 4000!
You need a bigger 3d printer for that one ?
Asking for a friend

Not at all.
Because I have gobs and gobs of .....
Well, I'm hoping that in the next week or so the folks in the know will come up with a way to keep most/all folks from dying from this contagion. In the meantime, I'm doing what I can to stay occupied with something constructive. Of course, with my ADD, I'm all over the place. LOL. ... SQUIRREL !!!
Worked on a design for a 20mm wide drag chain last night. I think I have that nailed down good enough for my purposes. Just need to print about 20 links at 20+ minutes each.
But this morning, I spent time tweaking the Z Axis design for the CNC. I think it's coming along pretty well. Used a couple of your ideas.
ballscrewbob:
As for loosing X travel maybe a relief for each of the rod holders and an X axis screw mount relief.
Not too sure what dimensions you have but it may give you a little of that 25 mm back ?
Yup. Gained a bunch back. In fact, I think will have more than I did originally, if that's possible. Never really accurately measured the original travel. But with this design, I should be able to get a full 300mm of X travel.
ballscrewbob:
Mine has about 5mm inside between the bearings and I just got some nice small grease nipples so if I poke a hole in there I can lube both on one rod from a single point.
Added some tunnels for adding grease. I have to pick up a couple of zerts to get measurements for the openings. But the tunnels are 3mm dia.
Only problem I'm seeing at this point is the fact that it is going to take nearly 4 days to print!!!! :o Going to look into ways to do it in chunks. But I'm not hopeful there is a way to do that and maintain strength. But maybe?
Looks good. Just some points from me:
Greasetunnel: place them in a way that you can feed them from top to bottom, i.e. do not add a tunnel that needs grease to go up against gravity. reason: grease will flow (temperature, vibrations ,...) so it's good to know that it'll en at the rods, not the desk.
X-Axis, top rod: move it up. It'll reduce flexing in Y-direction.
Rods: can you use supported rods? --> less flexing.
Z-Axis: use 2 bearings per rod, not one. --> less flexing.
Z-Axis, motor mount: do you use a stepper with TR shaft? if not, where do the couplings go?
Just my 2 ¢

I appreciate the input. (I've lettered your points).
-A- There will be fittings (zerks) for using a grease gun in those holes. So, flowing out is not an issue.
-B- If I move it up, then I lose clearance beneath it. But I do see your point and will have to decide if the extra clearance outweighs the possible flexing.
-C- Not sure what you mean by "supported rods".
-D- The motor mount on the Z axis does uses 2 LM8SUU bearings per each rod.
-E- My machine is a Chinese 3018. You can see in the photo below how the stepper is connected. I'm using the same method.
@C: just got lost in translation ... I mean stuff like this:

or this:
@E: OK. I don't like these standoffs, better design a cage that fits the NEMA17 flange perfectly. You'll relieve a lot of stress from the mounting plate.
The 1310 I sent to a friend last week has everything built from aluminium (fine quality, but maybe I was lucky). The motors are this type:
Makes the build quite clean, but I don't know how they last.
@ Clearance: if you mount the spindle motor on the part where the stepper is now and move the x-bearings to the part where the spindle is now, then you get more clearance at the cost of more buildheight.

I think that may be a bit overkill for this little machine. I wasn't even going to get as involved with "upgrading" this thing as I have, but my spindle took a dump on me. The new one is larger. So, I had to come up with a mount for it. It just sort of snowballed from there to where I am now.
@E: OK. I don't like these standoffs, better design a cage that fits the NEMA17 flange perfectly. You'll relieve a lot of stress from the mounting plate.
The stepper motor standoffs ARE NOT going back on. 
I made sure that I have enough travel that those chincy little things are in no way needed.

Pretty much identical to those on these 3018s. Nema 17.

Not sure I follow you there. But if I'm on the same page, I think that would make the whole Z carriage quite a bit wider. And I would have to come up with some sort of custom rod mounts. Doesn't quite seem feasible in my mind.
That looks spectacular.
Way better than the Chinese version and probably 10 times stronger.
As for the grease tunnels May have been tempted to just put it directly in line with the center of the bearings and probably not even bother with a grease fitting but just use a regular cone nozzle to inject the grease.
It is not going to get hot enough to "flow" anyway and only get used once in a while.
Truly am impressed with that and think you may have missed your calling.

Directly in line wouldn't work. The bearings are too close to being aligned with the cross beams. But, since posting that about the zerks, I've been doing some research on the idea. Yeah, not using zerks. I'll print up a little plug or something. Not that the zerks are expensive. Just cant see buying a big ole tube of grease and a grease gun just for that purpose. And like you said, it'll only be used once in a while.

Thanks Bob!
Actually, I have a Bachelors in Drafting & Design. Albeit, I received that a long time ago!!!
Got me a baby grease gun for some garage work a looong time ago and it came with multiple nozzles so now it occasionally get's to visit the house too.
You should have no shortage of lube / grease anyway

I have (or had) one of those. Haven't seen it in a coon's age. Might have left it hanging in the garage at my ex's when I moved out. Who knows?
