hello everyone
I design one power switch, which can be put in place of “Small Corner”.
no need to make additional hole in 3d frame, only take out one small corner and put the power switch.
My power switch I bought here in Sweden, but this model is possible to be found in any electronic store

Thanks for sharing. I was actually working on a design to make this switch (link) fit. It lacks the fuse but is a bit more compact:
How have you wired this switch?
Thanks, I found same what was used by @zannddor from local store. http://www.partco.biz/verkkokauppa/product_info.php?cPath=14_1501&products_id=9157
After the print is completed some wiring and it should be service. For the fuse I’ll try 630mA slow.

I think 630mA is very low, I use 10A
For the fuse 630mA slow is fine, tested and in use with IKEA LED’s directly from 150W power supply.
Naturally without heated bed but as soon as simple enough solution merges I’ll need to adjust the fuse or use additional external PS.
For the ones interested in the power consumption of the printer I made a few tests with my watt-meter.
Printer idle : 23W.
Printing with 1 nozzle : 60-90W
Printing with 2 nozzles : 100-120W

One nozzle is pretty much as they told us (5A @ 15V = 75W). Judging by your figs we can take 110W as the power consumption with two nozzles. That’s still pretty cheap over a ten hour print…
Does anyone know how many metres of filament are on a roll of 1kg Velleman PLA 1.75?
To know the length, the math is quite easy :
PLA density is 1.3g/cm³ - ABS density is 1.08g/cm³.
The filament has a diameter of 1.75 mm. The cross section surface is then 0.02405 cm² ((0.175/2)² x 3.1416).
1Kg PLA is 769cc (1000/1.3) and 1Kg ABS is 926cc (*).
To know the length :
PLA : 769/0.02405 = 31975 cm = ~320m
ABS : 962/0.02405 = 39976 cm = ~400m
(*) edit : sorry I had swapped 2 digits : it’s 926 and not 962.
I have been working also on very similar design. Since I was not able to acquire that compact component from the local store, I decided to put the power switch on the side and the connector to the rear. There’s not much space though… we’ll see how all the cables fits!
I tried to match the curvature of the mounting with the Vertex opening by eye 
and designed a snap lid to make it “safe”. Propably it would not pass any IEC standards though…
I can share this later once I have confirmed the design.
The lid is a good safety addition i agree. I used heat shrink tubing on my setup, double isolated it, should be ok i guess but no EC rating haha…

Handy to know - I paid about £23 a kg, so about 7.1p a metre. It’s all turning out to be much cheaper than I thought it would be to print things.
