How can I get honeycomb as an exterior fill pattern too?

[WhiteHare]

The purpose of this particular gizmo is to completely eliminate the audible PWM fan noise on the Prusa I3 MK3:

Now it can finally be silent.

In addition to ventilation, the honeycomb also allows me to read the frequency and duty cycle on the internal LCD display, should I wish to.

Looks good! We appear to have a somewhat similar interest in gizmo's https://www.youtube.com/watch?v=Sezbbfo ... e=youtu.be

Nice! Looks like you enjoy mechatronics. I suspect you would enjoy building your own CNC machine. The MPCNC is one where you can print most of the parts on your 3D printer, but there are plenty of others also that you can find on thingiverese. I purchased a 2418 kit from china (less than $200, including speedy delivery to my door by DHL). I use it to etch PCB's, one of which you can see above. It's pretty cool what hobbyists can do these days: if you can dream it in enough detail, you can probably build it too.

Thanks for the input/MPCNC info.

I have a 3-axis CNC mill I’ve used for PCB’s and consulting projects for 15 yrs.

The largest I PCB I can mill is 13 x 6 inches which is large enough for anything I need (and, can do double-sided PCB’s). I thought about making something like the MPCNC but my machine is so accurate/dialed-in that I fear it would feel lonesome sitting idle.

I fixture’d an Ink-Pen to a 3D printer for inking photo paper for a transfer/etching process. Also, I used various software’s and (Eagle) Plug-In’s for milling PCB’s. Then, I discovered “CopperCam” and was able to use my CNC - that’s all I use now along with Fritzing (Yeah! No more fussing with Eagle/KiCad/etc).

Most of my PCB’s/electronics end up in a 3D-printed box/mount that I use Simplify3D for. I built two Prusa i3 MK8’s from Hictop kit’s and modified the Marlin firmware…

So, between Simplify3D, Fritzing and CopperCam, I’m a happy camper…

As far as dreaming; fan’s in my machines are loud and you’ve given me a new idea for a project - new, quiet fan’s. Thanks!
