Raduino reinforcement, 3d printed

_Dave_ K0MBT
 

I have noticed particularly on my ubitx radios that the raduino board is just hanging on the 16 pin connector. Very bad engineering to not have a mechanical mount.

The other day while putting together another radio I decided to make a mechanical mount for the raduino. I used 12 mm long 3mm screws and nuts to hold it together. It is using stock front mounts with the original screws replaced by 12mm screws.

I think it is a worthwhile modification. The part could be made from metal but was easy to make from plastic.

I am going to make another one for my bitx40. I imagine that the length will be different.

Great idea and looks good to boot!

Looks great, however, I can't see if your PA heatsinks are touching
the chassis. If so I am sure you know that they need to be insulated.

Awesome

Good Eye Laurence

Those heat sinks are going to go, too small. The board bought used had them on. He did a beautiful job overall. He isolated the heat sinks You can see the plastic collet at the screw.

I am going to remove the heatsinks and put an aluminum plate behind them and bolt through it to the aluminum chassis. But first I am going to get the holes cut in the front panel. I am printing a plastic template of the front now.Using it to mark the holes.

Did you print that bracket? If so you might consider sharing that in the files section...

Yes it is printed. Never tried putting anything into the files section.

I need one of these printed in Black, anybody know where I could get this done?

3D printing has become a home closet industry.  Google terms such as" Who can print my 3D close to me" and you should be able to find a number of folks to get quotes from.  All you need to do is provide the .stl file.  Prices may be all over the ballpark so don't be surprised at the answers.  Pricing will probably be based on a one time setup, cost of material per gram (perhaps $0.05) and a cost per minute or hour for printer time (perhaps $1 or $2 per hour expressed in hours and minutes)  3D printing is not fast...

Another thing to consider is going down the 3D rabbit hole.  An Ender3 is under $200, and filament is $20 per Kg roll of PLA+

I finally took the leap a month ago and wonder why I waited so long.  I found a local (to me) Facebook Group for support.  Yes there is a bit of a learning curve, but once you get familiar with operation and the tons of .stl models available (free!) on thingiverse you will probably want to start creating your own models.  There are a number of free modeling packages with different capabilities (learning curve) but youtube is loaded with excellent tutorials.

A couple of the public libraries around me have 3D printing ability listed as services available at nominal cost. 

I have yet to try them though I have 2 TFT bezels to obtain sooner or later.  You might see if your local public library system hosts this capability as well

Tom's absolutely right about the 3D rabbit hole.  Be careful if you do though, These buggers can be extremely addictive!  Fortunately I have family support (my wife likes the Rose & Stem (stole it from Thingiverse) I printed for her shortly after she bought me one for my recent birthday.  It had a rather small print volume though (4.9" cube) so I spent another $217 on an Ender 3 with the glass (non-warping) bed as a second printer for the bigger stuff.

I don't have any black filament right now or I would have volunteered to print that for you.  Also they same guy that sells the little AGC board does them too and since he's doing them commercially and graciously sent me the .stl file I didn't want to encroach on his business.

 Staples would be a good bet for me.
 However, I have the drawback that it is 60 miles from me, and I cannot afford the trip most of the time, much less added cost.
 I had a bad weekend with my Truck, which cost me some $$ for parts, plus I was kinda looking at old Macintosh computers on Ebay, and happened to decide to look at GE Suitcase programmers.
 I have one, but the HHC (hand held computer) was blown, as well as the power supply, by roof leakage, dang...
 So I looked at Panssonic HHC's on Ebay, and found one with power supply and stuff for a low price.
 Except it decided to not want to turn on when the seller tested it once more before shipping.
 We agreed on a partial refund, and I looked at another working HHC, for a lower price, and a make offer. I made an offer, he countered, and I have bought it.
So have blown my funds for a good while, with other stuff.
 I do like the 3D printing, though I don't really like not having metal cases.
 But would be great for stuff like bezels and more.

 

I have found several places around town that do 3D printing including Staples, so its just a matter of finding the best one to do the job. I may consider getting my own printer too, (probably a Ender 3), but I'm not sure how often I would use it. Who knows, maybe I would find all kind of things to print. Another problem is, I have a rather small shack/shop and don't really have the room to have it sitting around collecting dust.

I printed these for club members with ubitx radios. I don't usually print black. It does terrible outside without being painted. Summer sun will melt it in 5 minutes.

I have had an Anet A8 printer. Paid 153 for it 3 years ago. It isn't expensive to get into. Have 2000 hours of printing out of it. Maybe a couple of dozen rolls of filament. Have tried ABS but didn't like the warm up time. With ABS the bed needs to get to 100 degrees, and the parts seem more likely to warp when cooling so I print with PLA. Be aware that printing 3d is not like printing on a sheet of paper. There are a 100 reasons to fail. It can be from a poorly designed object or a mechanical issue with the filament, dirt or the machine. Just ask anyone who has one. Mine will print happily for a couple hundred hours or more and then something goes haywire and needs to be adjusted. It takes about 40 minutes to print even a small part like the raduino bracket.

The real fun isn't the printing but the designing. I use Fusion360, a professional grade software that is available with a free license for the hobby and small business designer. The trick with designing something is that it should be easy to print. I use Repetier Host as a slicing software. Have tried several others but this usually sets up the print best.

Once you figure out what you can make you will be amazed. Take a look at thingaverse.com and you might get an idea. It isn't just for radio but most any component that is in a non hot location can be designed. All around our farm we have printed parts and brackets. Go to the hardware store trips have been greatly reduced.

I thank David for his design and for making the .stl file available.  I have just ordered four brackets from a local 3D printing service.  Beats buying a printer with attendant problems of assembling, setting up, adjusting, as well as finding space for it, and avoiding "discussions" with the beloved.

I am glad that other ubitx enthusiasts are getting benefit from this project. Just a bit of payback for what I have learned. Thank you Farhan, Dr Lee and all other operators.
