because its not sticking to the bed well so there are few void spots. where it sticked, it brought some of the blue tape with it, i have to postprocess and sand it to get better finish result. i've not used my printer for some time.. and its abs, abs gives me bad result. whats not obvious is the warping effect. i can get better output if using pla, but i want to finish up my abs supply first.

I'm a month into 3d printing (first machine, still learning). its not easy and it takes getting used to the brand of filament, your machine, slicer settings, so many things.
I only print PLA, so far, and while its the 'easiest' thing to print, I still get warping from heat on some corners, on some larger items. on small items, its no problem.
build-tak is helping. I had mixed luck with blue tape but it would bubble and lift under heat (not even heated bed) and its a hassle to keep replacing the tape. try build-tak stuck onto a piece of glass.

Made my case for M328 tester with color display.
I used following components:
- 18650 LiPo-Cell from broken power-bank (connector broken, cell ok) 2000mAh
- Loader for Lipo with USB-connector
- Step-up converter to 5V to power the tester
- Step-up converter to 26V for Z-Diode test
- The button on the left cuts power when pressed, if the MCU hangs.
- The test-socket sits on a adaptor-board to lift it up, and the bottom row has 2221333 connection for different IR-decoder pinout.

Got the colour just right, it was printed before the Agilent arrived.

Maybe I spent too much time helping graphic designers calibrate their displays and printers back when I did tech support, or maybe I'm just an intrinsic color nut, but to me, those are noticeably different shades of orange. (That said, I assume 3D printer filament comes in a couple of colors you have to choose from, and for not having the Agilent in front of you to compare, it is a close match.)
cdev:
I have mine in the cardboard box that my Raspberry Pi came in. The hole for the display, test button, and ZIF socket is covered with a cardboard cover made from a frozen pizza box with a bit of velcro to hold it shut when not in use. I also use a rubber band to keep it shut. This works well. I have used cardboard - sometimes combined with copper flashing or tape, when shielding is required, to protect projects for a long time. If something isn't meant to go outdoors, and doesn't run hot or contain parts that are connected to line voltage, it works very well and its very easy to do. I save pieces of cardboard that are bright colors or have some interesting image on them so the boxes are colorful.
