Delta Elektronika DC power supply CASE DESIGN FOLLOW UP

The topic and idea: to design and order parts for new case, check out price and quality,
most home electronic DIY persons dont have metal laser, metal cnc, metal plate cutter, or a metal sheet bender, or even know how to bend metal plates perfectly to the last super accurate measurement, so i wanted to try skip all that, and just order the parts. bingo bongo done,
all you need here is no skills, just money..
I also tried to ask PCBWAY to paint my parts, they can also do that, but it was too expensive.
So a little DIY was needed, the reduce the total cost,
I wanted to order the right color of paint and figure out how to spray it.
I measured original plates as color Pantone 419C,
Flugger (local paint expert company) measured the color to RAL 7025,
3D design software Fusion 360
Budget brake down :
All 4 metal parts PCBWAY including tax and shipping 208 $
Paint and color measurement at Flugger 250 DKK = 37 $
Paint Spray Gun from Jem & Fix 160 DKK = 24 $
Water seperator from Biltema 160 DKK = 24 $
Aditional Fittings from Biltema 90 DKK = 15 $

Det kaldes appelsinhud. Du skulle slibe første lag maling med vådslibepapir korn 1000 eller 2000, men et flot resultat du har fået. Jeg kan godt lide den overflade.

Really good job on the paint.

[@ralfstocker7742]

Brilliant job. The price of $200 is beyond DIY. Only worth for very high-quality devices.

[@migsvensurfing6310]

As an engineer in Denmark that cost is nothing.

[@TeardownOZ2CPU]

how people feel a price is ? is relative to each projecs budget ? if you are elon musk, you might not think 3 sec about it :-)
my point of this project was to show how it can be done with out access to any type of tools or machines, since they cost money too, and they fill up alot of space, and space you have to pay for too, you workshop area cost money pr square meter every month too, calculate it all, and maybe this 208 is very cheap :-)

@@migsvensurfing6310 The device price and the metal housing price should be 80:20 and not 20:80.

paint was too thick,this causes the spotty texture...sand it down with water to absolutley flat,mix paint with 10 to 20% thinner and re flash the parts...keep the fan wide using around 70psi........i was an industrial spray painter for 20 years,after the electronics industry in Scotland died.🙂

[@jonscally2349]

you can obtain various types of finish,dependeng on preferance.

[@TeardownOZ2CPU]

thanks a lot, i will experiment much more with this type of psint and mix it thinner , and try sanding between layers, as a propainter, do you only paint stuff once ? or two layers ?

[@TeardownOZ2CPU]

@@jonscally2349 also a good point, the fun thing is : alot of electronics got exactly this paint surface i created by accident :-) or random luck, depending on how you look at it, it surely was not skils, since this is my first time using a paint gun

[@Nixie_Claus]

@@TeardownOZ2CPU This is the surface is expect for an electronic device like this one. Nearly all my cases look like this. I like the paint job!!

[@janschrder]

Well done Thomas, well done indeed :-)

[@inse001]

$208.- is a hefty price tag imo.
I would bend it myself and forget about the fraction of mm accuracy.
It’s lab equipment, not furniture after all.
But the result is nice, no doubt.

[@TeardownOZ2CPU]

do you have a bending machine ? do you have a plate cutter ? can you put all the holes exactly as accurate ?
was the bending machine for free ? how much space will it take up, you pay for this space every month too.. if you think about it

[@inse001]

@@TeardownOZ2CPU No, I don’t have those tools, a local workshop let me use their bending bench and guillotine shears after hours.
For smaller stuff, I cut the aluminium sheet with the table saw at home and bend it in the vise or with clamps and wood support.
This works OK, not for sub mm accuracy but I tolerate that ;-)
Holes are drilled a little larger to match.
