Lightbulb Any interest? 11 Y/O son just made a prototype, works great! Garmin GRID 20 cover.

Garmin GRID20 controller... which is this thing, if the horizontal model:


Or... this (if vertical):


For some reason Garmin doesn't make a sun cover for it... I thought... Hmmm... my kid loves messing with this stuff, so he created a prototype sun cover. The prototype is in PLA which is NOT a good idea when sun, heat, etc. is involved... so we have another material coming that is UV stable, good for heat, etc. etc. etc... Really good stuff. It will be white.

This was printed at a faster speed, so the finished ones will look a little better, but they will still look 3D printed a bit.

Thinking $20, maybe $25 free shipping... ? I want to see how this new filament prints first.

Please be critical... he's tough and the harder you are, the better. He strives on it!

My grid looks quite different from yours. I think a flexible molded product would be immensly cheaper to make in bulk and have a significantly cheaper selling price. I would not pay $25 for a cover for the grid, but then, I have a T top that shades it 75% of the time we are out and a cover on the boat the rest of the time. I also have a canvas console cover. I would pay $7. for a cover. I only replied because you asked for truth. I am just 1 of thousands of people so take it for what its worth. The GRID is the only thing that didn’t come with its own cover and I assume that means it doesn’t need one.

Why don’t you model the GRID itself and get some kind of polyolefin sheet product, shrink it over it, trip it and see how that fits as a cover. I bet you can make them very quickly and sell a ton of them.

This is what Mine looks like. https://buy.garmin.com/en-US/US/p/102804

Thanks. Yeah... yours is the GRID, the GRID 20 is a different unit.

As far as price... The C10 (Simrad) tiny covers are $20 and they are half the size and weight. ... but appreciate your input.

Just a thought but if the finish doesn't come out as good as you like, can you use parchment paper and a clothing iron to smooth it out more? Just a thought.

Looks good, I would however recommend putting a little bit of radius (rounding) on the edges and corners on the outside to make it a little less sharp to the touch.

the new filament is called ASA itís like ABS but better... Iím not sure you can do that... but I think he can get it much smoother when we go from Standard to Fine.

this was a quick and dirty to check his caliper work.

I've done many 3d prints at work on our printer that can print as fine as .005" and the parts are not waterproof. The problem is you cant get rid of the printer lines with this type of printer. The only way to do this is to seal the surface with a glue like filler and sand it smooth. Not sure which printer he has but I will assume one of the desk top ones which will not produce a smooth line less part. For personal use it's fine, but not sure buyers would accept them.

First excellent work for an 11yo! My applause. Lots worse things he could be doing.

id remove the knob. It’s clunky makes storage difficult. Put a grab edge on it and perhaps a finger groove.
not sure what the printer is capable of, but look into a finger pull bit or chamfer edge. It will look cleaner and more importantly cost less in materials and may be faster in production. I was about his age when I started woodworking. Now I have a decent side gig going. Could probably make a career of it but I love what I do.

again great work To him! You’re doing a great job dad. He may want to start making various screen protectors if this works. As well as sun-visors for fish finders etc.

Sorry... yeah, the picture of the GRID 20 is terrible... I should take a picture of the actual item.
The GRID 20 has a joystick that sticks out (you can twist it as well as it has up, down, and push)... so that protrusion you see (the "knob") is actually there to conform to the front of the unit.

--

Other replies, I an tell you that with a smaller nozzle and going from the "Standard" to "Fine" the lines will not be that crappy... Right now the next step is to get the ASA (new filament) and see what the learning curve is on that.
I also appreciate the offer for the Fusion cover... we don't have one of those units, but I'll take a look and see what it looks like... never know. (I'd have to bring him to the store measure it, then go back to fit it, etc... so it's a long shot... but... never know...)

Thanks for all the input!

If he refines the design a little I think it's a good idea.

I also think selling up stream before actual users is a better bet. If an electronics installer is doing $20k worth of electronics with covers on everything except the controller, adding a $25 item for the end customer to be happy with covers for everything is easy. Getting the same customer to care enough to spend time ordering the cover from your son is a harder sell I think.

Electronics installers, manufacturers, etc. I would think are the better bet for sales. They'll call him each time they install that controller if the product is good.

Thank you guys! Hopefully the new filament will be here today and I give it a go. We've never worked with this stuff, and it is A LOT different.

The stuff, if it works, is crazy-cool. UV resistant, weather resistant, etc. They use this stuff to replace parts of weather stations, boats, etc. I also have to find a place to put the printer since it's not a great idea to do it without ventilation.

Just wanted to say that you should be a super proud dad, and you are doing an amazing job motivating your son to think out of the box and do what he likes! Keep nurturing his talents and I am sure he will be very happy in life.

In regards to the product itself, If I owned a grid and Garmin did not provide me with a cover, I wouldn't mind paying 20$ for a cover. But as someone above stated I would prefer it being a flexible molded cover like the Fusion head unit covers.

But again, If there were no flexible molded covers available I wouldn't mind paying 20$ for your sons cover!

Goodluck! And please continue to motivate him to create and innovate!

Thank you for the kind words. They are very appreciated! Now... if only I could figure out how to connect with my daughter. But that's another thread, for another day.

BTW I am impressed that he can do this stuff, 3d can get difficult, one more suggestion, maybe a bump out on one side to help with removal, just a finger notch so to speak

Thanks.

In full disclosure he does the CAD work, measures the item, etc. He is using TinkerCad, and is slooooooowlllly making his way with Shapr3D (which is totally awesome BTW). Then we sit and put it in Cura together and he makes the call of certain things like supports, researches temps, etc.

Then when it comes time to do the actual 3D printer, we do that together (which is usually just leveling the bed with the paper method, and keeping an eye on it).

I'm trying to think about where to do this safely with the new filament. Apparently the ABS/ASA stuff isn't the best stuff to be melting in your house. LOL.

He's made some other cool stuff that solved real-world problems... even presented one of them to his school... I have to say, the remote school thing really fostered some cool stuff.

Thanks again for the kind words - I've been sharing them with him. Hopefully I'll have some positive things to report on the 2.0 of this thing.
