6th Annual Scratch Made Light Contest - Flashy Mike's machined project

Looks interesting, I hope you do get it made in time :+1:

Subscribed :wink:
And don’t forget to PM =the= for your thread to be added to the contest!
Good work :+1:

Nice idea! This will be a very unique lantern for table-top lighting!

Here’s an idea: Do you really want to make everything 3D printed? You maybe could use a piece of aluminum to make the reflector cone. If you can find a thick enough piece of Aluminum plate or bushing/washer, you could drill a center hole (if using plate), put a bolt through, and spin it on a hand drill held down with clamps. Then file the cone shape with a hand file while it spins. After, maybe you could 3D print something to plug the hole that will also be the hanger for the top.

Good luck Mike! What printer do you have?

We are living in a flat, unfortunately without a dedicated room which is suitable for metal working. Neighbours won’t like me using machines here, and I won’t like the cuttings all over my room.
Apart from that, I really like the idea to use as much 3d printed parts as possible, as a proof of concept.

Btw., I don’t see an advantage in using aluminium for the reflection shield. I need diffuse reflection, just like the ceiling of my room, and the aluminium won’t be much better for this purpose, I guess. It mainly adds weight.

Its a Creality3D Ender-2:

A very nice device, small, mostly prebuilt and with a reasonable price tag. I like it a lot, did some improvements meanwhile. The little thing is printing all the day …

Whether you finish in time or not to me doesn’t matter.
I was looking at your pictures thinking they looked pretty good when I read they are pretty rough. I’d like to see your good sketches. :slight_smile:
All the best for the build and the surprise.

Well, my thought was that you might want as much reflection as possible, even if (or especially if) it is diffuse. But I understand your limits on machine noise and dust/debris. It should work well enough with the reflective paint I think. I’m looking forward to seeing your build.

Nice entry idea :+1:
You may want to consider Chrome MonoKote http://www.monokote.com/metallic.html
You can heat shrink it tight on the cone for reflection. I used this Monokote when making RC Planes with my son yrs ago. Use a light heat gun to shrink it tight after super gluing it down around the edges.

:beer:

I have the same printer, indeed a nice and small device. What improvements did you do? Lately I installed a E3D V6 clone on mine together with a firmware upgrade to the latest marlin, have not printed a lot after the change but the few prints I did came out great.
Also did some smaller upgrades like belt tensioners, filament guide and a tilted lcd mount.

Do have to say that I kinda expected a little bit better print quality out of the box after seeing many reviews. But I do like this small machine!

Up to now only the simple ones, like filement guide, silent fans for board and hotend. Designed and printed a small plate for the bottom of the hot end to stop the fan blowing partly onto the printed object (when using ABS). Designed and printed a simple filament roll holder since the filement string had too much tension when pulled from the holder on top of the Z-Axis.
Haven’t changed the power supply’s fan yet, since it was a too tight fit with the ordered silent 20mm fan (stock one is 15mm). Still looking for a fitting silent 60x60x15 fan with suffizient flow.

Got the green ABS for the lantern yesterday, currently searching for the best slicer settings.

Looks interesting. I considered making the cone of two parts anyway, so I could hide the glued foil around the edges with a flat plate on top.

Good luck with the build, Flashy Mike :+1: :beer:

Unfortunately I haven’t done much for this build in the last days but I got more familiar with 3D design and printing. I created my first designs with Tinkercad which is great for beginners but lacks features for advanced designers. So I downloaded Fusion360 which is more capable. As in other products of this company I had my problems with the user interface but was able to create my first design after an evening (and after lots of grumbling and google search).

To learn more about the capabilities of my printer - and in order to know what I can do in my camping lantern design - I designed and printed a couple of screws and bolts in different sizes. Turned out surprisingly well, the smallest one in this picture is M3!

First prototype of the mechanism for the rectractable reflector. The thinner component will be screwed at the top end into the reflector. Prototype is shorter than planned for the final build in order to save filament and time during testing. Perhaps I’ll add one more segment if necessary. Currently printed with PLA, probably will be made of green ABS for final build.

Can’t see 2 of the pics but looks like you’re making progress :+1:

Nice project, the first contest entry as I remember that will heavily lean on 3D printing :+1:

Which of the pics can you see? There is a green rendering, and 2 fotos with orange parts, one of the fotos with 2 separate components. I’m using google fotos for this pics and there might be a problem with links.

On my laptop I can see all the pics.

On my desktop, this is what I see:

Thanks! I guess I found the problem, all 3 pictures visible now after reload?
