3d printed case advice? #flrig

Randon Loeb
 

Are there particular gotchas in cases for ham-related pis? I don't plan on any hats, idea will be just flrig 
to control ft-891 and audio via usb sound dongle, maybe usb gps for time. 

Other than the usual ventilation for these hot-running pis, anything else I'll wish I had planned for? Only 
other thing I can think of is maybe to have the case hold the buck converter for the 12v->5v.

I will 3d print it myself, have done so for a handful of 3b+s for various uses, though could buy if price is not ridiculous.

Thanks

Great to have another 3D printer and RPi person in the group.
Top photo shows the orange stand printed for my CS108G+ and ham shack buddy.  He was around a 18.5 hour print.  My 3B+ runs hot, so printed a case that could accept a cooling fan.

Check out KM4ACK on youtube..  Has some good videos and scripts for loading just about any ham program on your RPi.

Only issue I've found is that it can't run netlogger.  No version available for RPi ARM processor.

Literally 5 minutes ago dropped KM4ACK a question about mumble server on one of his videos. My goal will be to use mumble for voice and the ft-891 controlled by the pi remotely. Fan, and extra heat sinks on the usb ports.

Here's the case I made for my dmr pi.

Bought the aluminum case for my 4B / 4G Pi.  Case does get warm.  Have couple of small 12vdc fans blowing on radio and pi case.  The cs108 runs hot when using digital modes even at roughly half power.  Printed support legs for fans, mounted on floor samples from home Depot.

Another link for RPi scripts:

Like the 4b dual monitors support.  Comes in handy for digital modes and such.

Never tried  mumble server for remote operating.

Have played a bit with NoMachine software.  See March 2020 QST issue.

Looked at your comment / question for KM4ACK.  Understood basics.

Running pistar or similar for the DMR?  Case is pretty cool.

Been making a lot of ear saves as well .  Using flexible filaments for more comfort.

Have ender 3.  Added BLTOUCH sensor.  Was working pretty well.  Started getting min temp error and other stuff last couple of days.  Going to reload firmware and check some other things tomorrow.

Using pi2 running octopi server for controlling printer.  makes it easier for remote control.

I've printed a couple of different Raspberry Pi cases one that I've found on Thingiverse.com or Pinshape.com.

One has a mounting for a fan (15mm if I recall).

The other is bigger and has a cut out/bezel for a 3.5 TFT color display.

Maybe some mounting holes or brackets ?

Maybe space within the enclosure for the USB sound dongle and a short USB cable ?

Like these meters for power monitoring from eBay.  Mine are 20 amps, no shunt.  The 50 and 100 amp models are basically same but have external shunt.  Couple of different case styles printed for them.  Second photo have used Command strips to hold  meter in place.

Inexpensive 12 VDC fans from hamfest, think paid around $1 each.  Printed legs.  Do good job keeping radio and RPi, if needed, running cool.

Initial check on thingiverse site, couldn't find any designs for this board.  If you can provide link to a design file, could print one or two for your group.

Extreme beginner in trying to use tinkercad or similar 3d software for designing anything.  So have to pass on that part.

Tadd-
What software did you do the PCB with? Many of the newer PCB layout software (KiCad, Eagle) are parts of suites that can output a 3d design file of the board populated with components, which makes it easier to create cases.

You raise a good point here about maybe building some cable/dongle management and strain relief into the case itself.

I like this idea of combining the various peripherals with the pi under one large fan. I was thinking too it isn't really necessary to go the "usual" route of cooling the pi off a 5v fan, may as well just tap the 12v and go with a more powerful fan.

Like these meters for power monitoring from eBay.  Mine are 20 amps, no shunt.  The 50 and 100 amp models are basically same but have external shunt.  Couple of different case styles printed for them.  Second photo have used Command strips to hold  meter in place.

Inexpensive 12 VDC fans from hamfest, think paid around $1 each.  Printed legs.  Do good job keeping radio and RPi, if needed, running cool.

I've printed a couple of different Raspberry Pi cases one that I've found on Thingiverse.com or Pinshape.com.

One has a mounting for a fan (15mm if I recall).

The other is bigger and has a cut out/bezel for a 3.5 TFT color display.

Maybe some mounting holes or brackets ?

Maybe space within the enclosure for the USB sound dongle and a short USB cable ?

Subject: [RaspberryPi-4-HamRadio] 3d printed case advice? #flrig
 
Are there particular gotchas in cases for ham-related pis? I don't plan on any hats, idea will be just flrig 
to control ft-891 and audio via usb sound dongle, maybe usb gps for time. 

Other than the usual ventilation for these hot-running pis, anything else I'll wish I had planned for? Only 
other thing I can think of is maybe to have the case hold the buck converter for the 12v->5v.

I will 3d print it myself, have done so for a handful of 3b+s for various uses, though could buy if price is not ridiculous.

Thanks
