355 3D Printed Ashtray Project

Finishing a 3D PLA print is really quite easy. My steps to a smooth PLA print: (Using Amazon Basic black PLA)

1. Prime with a rattle can. I use https://www.amazon.com/gp/product/B002984MU0. Nice color too.
2. Wet sand with 300 until color from the PLA shows. The point is to fill the lines, not change the dimensions.
3. Prime again.
4. If lines still visible, and generally, there's a few areas that need extra work after the first go, repeat at 2.
5. Lightly wet sand with 800.
6. Add finish coats to suit.

The less work put into finishing, the better the dimensional results. Sanding can take enough material off to make something not fit right so the idea is to add just enough paint to fill in the grooves and to sand just enough to remove only primer. The net dimensional change is near zero if done properly. This is fast process too.

I have a Prusa MK3S+ and usually print at .1mm layers. This makes the print pretty smooth to start with.

 

Oh so useful

 

I believe the newer cars, mid 98 ~ 99, need the ignition to be on.

 

That looks great

 

I need one of these. Let me know if you run a few extra

 

Me too as I don't have a printer

 

Wow! I too will happily purchase one.

 

Excellent post, thank for sharing.
Did you try to print it in PETG?
How much support does it need (I'm a newbie in 3D print). My program is generating a lots of them.

Wow! Put me down for one as well should you decide to make them available.

 

He's posted the part file.

All you have to do is download it and upload it to one of the many 3-D printing services available to get a quote (Xometry, Shapeways, Hubs, etc). Cost should be in the $50-80 range depending on material and speed of order (shipping).

 

I just installed Cura and with the tree option with 20% infill, it shows 10 1/2 hours!
PLA is indeed no good for car parts but I really want to try PETG. I've read it is OK up to 80°C. That should be OK.

 

I have a sidewinder X1 and I still practicing to get some results, so my speed is 60% for the moment.
I'm gonna order some PETG and try it. (I can' print ABS without a seal box).

 

Nice work, look very nice. Can you share the file?

 

Why on earth would you want it to drain inside your console? It's a GREAT idea, I'm just confused. No other automotive cup holder has a drain.

I printed mine in PETG (more heat resistant than PLA) in 13 hrs (100% infill).
Unfortunately it broke as soon as I fitted the metal cover on it.

Maybe if the metal cover were on same material, the flex would have been shared between the two parts instead of putting all the strenght on one of them?

Too bad, it was looking good otherwise.
(there was another problem: I couldn't fit the mirror control module aside. Maybe the rail underside is too small?).

So for the moment: back to the original broken/glued ashtray.

 

Nice work in this thread!

I found it because I had considered doing this and other bits of the console.
I also have an Ender (and 20years cad/plastic part design experience)

 

My original re-glued ashtray broke again.
I'm tempted to print another one, and find a late 360 plastic ashtray lid, so this way I won't break the ashtray when inserting the metal lid, like last time.
Unless someone is able to make a print file for the lid?

 

I could model the lid, if I can find time!
