V1 sBITX 3d printable case released!


 

Hi,

Just finished and tested my 3d printable case for the sBitx motherboard. This is based on the OEM case design from HF Signals and leverages the original work done by Mike (KW1ND).?

The preferred download is from my github at:?


In the? sBitx-case-3d-printer-files directory you can download individual stl files (and the Fusion 360 archive). Or you can go to:


Click on the CODE drop down in upper right and download all my3d printing designs.

This work is also hosted on Thingiverse at:


The github directory has detailed instructions and this is also provided as a pdf on Thingiverse that you can download in the files section.

This design in not perfect as the holes for the RaspberryPi are about 1mm too high. This results in a slight tilt to the RaspberryPi. I will fix this in the next version.?

There is also no attachments for an internal speaker provided (although there is a grill area for the speaker to the left of the RaspberryPi.) I have some possible candidates for a speaker coming from Amazon, if they work out I will re-release the design with the proper holes and provide the link if you want to buy the speaker (direct, not a referral link ;-) )

I also want to add a brace -- like what Elecraft provides for their KX2/KX3 -- so the sBitx can tilt back slightly.

Let me know what you think!

Here in the Northeast USA it is winter so for me a good time to focus on software development.

In the springtime it'll be outdoors POTA season and then having a cool case for the radio will rise up the list of things to do.

I definitely think having built-in braces for the radio to lean is a great idea, that alone will be worth making a new case.

Currently, I have a hi-capacity RC battery velcro'd to the area above the heat sink so the braces will need to be pretty robust since the battery makes the radio more top-heavy.

Just a thought: A friend of mine sends his designs out to a company that can cut them from metal, maybe the braces will need to be metal to be strong enough while being light as well?

I'll wait to see what you come up with, but I'm already quite enthused!

Dave - your idea of a leanable case is an excellent idea.? I have a few other QRP radios, and some of them have leaning cases.? Perhaps adding legs to the existing case somehow?

Since you mentioned batteries, perhaps those who have used them would like to comment on battery capacity and operating time per charge.? Might be interesting for new users.

It was Mark's idea first -- "I also want to add a brace -- like what Elecraft provides for their KX2/KX3 -- so the sBitx can tilt back slightly."

There are a few ideas I've seen on this group too.? There are the 3D printed legs that were posted here that I had printed, and some have simply drilled holes in the heat sink and used that to secure legs that let the radio lean.

Since you mentioned batteries, perhaps those who have used them would like to comment on battery capacity and operating time per charge.? Might be interesting for new users.

Battery tech is a deep topic and I am a total newbie when it comes to battery topics.

Having said that, I purchased?, they were a good value at the time of purchase, and having a spare seemed like a good idea to me.

I haven't operated with them long enough to quantify their longevity other than to say they lasted for a couple two-hour POTA outings and that's about as long as I want to operate.

I used "industrial velcro" to attach them right to the area above the heat sink on back of the sbitx.

The power lead is long enough to reach the sbitx's jack so they worked out nicely for my sbitx POTA setup.

I don't know if this helps, but:
I looked for the link to the legs someone bolted to the heatsink but came up empty.

Dave,

Thanks for the recommendations! I had actually printed a longer leg for my kx2 several years back. It seemed strong enough.? I was actually thinking of two legs, one on either side that had a crossbar attachment (think of an "H"). Having two unconnected legs is a real pain on flat surfaces as they are never aligned and the radio wables. On the otherhand, there are advantages to that for pota applications because surfaces are never flat...? Easy to make the crossbar an optional piece..

I think the H concept is good, but I'll have to see an image when one becomes available (no rush at all).

I haven't seen the Elecraft setup so I don't know what it looks like ( I know, how could I have lived this long without seeing that ? ).

Something that can tuck away is important for POTA, my V2 radio lives in a backpack.?

The current legs work quite well but are a bit problematic in terms of being kept in a backpack, I'm afraid they will break since they don't store flat.

One of my favorite radios ever had a U-shaped handle, but it could not double as a stand, although I have seen some that can.

Below is an image of that radio, for the nostalgic among us.?

My dad had one when I was a kid, and I stole it a lot because it could pick up the "beat frequency" of the local two meter FM repeater on its public service band!

I found some on eBay a few years ago, bought one for me and my brother so we could think warm thoughts about our late father.

Leg strength should not be an issue if printed in the correct orientation. If more strength needed, use a carbon fiber filament. ?

Thank you so much for doing this!? I have been looking for a V3 case since I received the board. I have an Ender 3D Pro and it looks like the bed is too small.? Can someone possibly suggest a good 3D printer company or companies that would print the STL files at a reasonable cost?

Thank you,

Mark, KD2XS


 

Mark,

I have had good luck with the services that thingiverse recommends when you download the stl files. I seem to remember a service called ninja something?? Looks like it is a group of folks with 3d printers that rent out their printers. Sort of uber for 3d.?

JLCPCB does industrial quality 3d printing. Not sure of the cost or timeframe.?

Hi Mark,
Thank you for the info!? I found the following in a Google search that seems like a Thingiverse affiliate:

There is quite a bit of variability in the costs of the various vendors.
Thanks,

Mark, KD2XS


 

I don't know if Mark or anyone else will take the bait, but my morning scan of social media found this really cool case for IC-705!

It has so many great ideas!

1) Flip-down screen protector that doubles as a sun-shade
2) Carrying handle on top (as per my earlier post, something I think is really nice to have)
3) Feet on bottom (not sure if they flip out, but that would be a good idea for easy packing)
4) Side grab handles (not sure this is as important, but they do protect the knobs if the radio falls flat)






If nothing else, some food for thought...

Apparently this is a product for sale in Japan.

The following link is a Google translation of their product page:

?

It has lots of pictures showing lots of details.??

If nothing else, it is inspiring me to start with Mark's files and add in some of the features of this kit.

Yet I am a total novice when it comes to CAD so it may be many months before I have something useful.

I guess it's a sign of obsession, but regardless, I've strip-mined the site and have included a PDF dump and all the photos in the attached zip file.

It's clear with the detailed photos that there is no handle on top.? I mistook the way they hung the screen protector as a handle.

Yet, still I think this kit has great ideas in it, and if I could get something like it for sbitx I'd be very happy.

And, yes, I still want a handle, LOL!

I'm rushing to make me a case out of red oak and purple heart. It will not be as refined as the one from HF Signals or a printed but sometimes you got to use what you have on hand.?

I just noticed one bug in this design…. The pocket for the encoder board was designed upside down. This put the vfo knob at the top and function knob at the bottom. There is enough cable to flip it right. ?Will fix this on next round.?


I really like that design presented above! ?Given that the holes for boards and phono plugs are all correct on my design, should be possible for someone to take my fusion 360 archive and add some of its features! ?Afraid my workbench has other things on it ?at for next 6 months so hopefully someone will under take the enhancements!

Good lord, is that green bar, tractor feed, paper it's sitting on? Wow, that's a blast from the past!

Thanks, Mark, for your enthusiasm!? I am consulting with a friend of mine that is a member of the same makerspace I'm in, and he's offered to help. I am more familiar with 2D so am considering seeing if I can't export your design as a series of panels, then add in some of the features of this design, then laser cut the panels and join them to make a box.? I am also taking a 3D CAD course in April.? So, while it may take many months to make progress and I also have other things ahead of this, I see lots of things I would like to do with your design going forward.

Many thanks for your amazing job.
?
?
I was inspired and used your design with some modification.
?
The major one is splitting the case into 2 pieces so I can print it with my new Bambulabs X1C Printer.
?
?
One of the advantages I found is it easy to assemble the board and also make some mods in the right side as I will not have to print the whole case.
?
I added on the front panel two switched for PTT and display brightness, and RCA connector and mounting provision for linear interface.?

Thanks again Mark and?
