dear 3d printing voodoo masters...

If 35mm is too much for your printer then just taper the inside in towards the top if permitted. I always design for no supports for FDM.

Can't be done with the clearances available.

You can taper (chamfer) to 20mm and bridge that and still meet the requirements. Also note that the internal depth is 50mm - not sure where that is referenced from.

i need a waterproof switch enclosure

Will a normal 3D printer deliver waterproof items?

That's going to depend on the conditions - pressure, temperature etc

 

[qwakers]

No pressure, ambient temperature, no chemicals.

It certainly can. I would have had a prototype in Nylon (because it's loaded) if the damn thing hadn't come off the print bed with 30 mins to go.

50mm depth is pretty arbitrary. I had to decided on a size and 50mm is a easy one. I just need it to be the depth of the switch plus enough for the cable to be secured and any excess to hide away.

Could always make it 2 piece so have the main switch tophat then a screw in plug for the back edge.

Would mean printing 2 items but could stand them both up and no supports needed.

Already in hand, with a screw in base.

That's the great thing with 3d printing. So many different ways to approach a problem.
My printer has been a solution solver at times.

Yes. The waterbowl I made for the cat is 3D printed - should be picture of it around here somewhere,

you're a legend

[qwakers]

that looks like it will work

 

[ajlelectronics]

Latest iteration printed on a raft. The remains of the raft are still stuck to the bed side surfaces. That's why it looks a bit rough. I could reprint with a brim instead to tidy it up.

Base is a nice snap in and will be fine with solvent adhesion.

Do you want another print done?

 

[qwakers]

that will do fine, can always sand it down if i want it smooth, but tbh it looks deliberate and kinda cool

how much do i owe ya?

Just pay it forward as we do here. PM me your details.

 

[ajlelectronics]

That's better, brim for adhesion and starting temperature 265/100 and dropping to 269/100 at 300m/s and 0.1 layer height.

It seems that I have more to learn about mating screw threads, but the bung is a really good, tight fit in the base. The male thread was fine on the bung, but the female thread in the tube distorted horribly, whatever I did. My suspicion is that a 34x 3.5 needs a much fatter wall, but I will revisit that sometime.

 

[qwakers]

no need to overcomplicate it, what you have done is perfect. I'm just researching methods to smooth the abs with acetone. its very interesting how many ways people have invented to skin that particular cat...
