after I fixed some broken connections on my self-etched PCB, it seems to work so far I could test. I tested an ATTiny 13, an ATTiny2313 and an ATMega8, so it should work with their respective MCU-families, too. I could not the ATMega 16 and ATTiny 26 family (but I think they should work), so if anybody rebuilds this project and test these MCUs i would be pleased when you write a comment.
I have released my design files under the CERN OHL v1.2 License, you can find them together with my modified bootloader and firmware code in this (https://github.com/jbtronics/AVR-ZIF-Programmer) GitHub repo
Finally some images of my board. It is self-etched with Sodiumpersulfate using the toner-transfer method. With the same method i put some silkscreen like print on the board. Additionally the board was tin-plated using some fittings solder paste:

Here are some Pictures of the PCB that I have rendered in KiCAD.
In the next few days I will etch the PCB, build it and test it. I will keep you updated.

I have not the time to test my Design yet, so I do not know if it really works ( but I think it will :) ), but I upload my KiCAD Design already ( They should be in the Files Section now).
When someone finds mistakes, have improvements, or even build the Programmen then write it in the Comments.

Finally I have finished the Schematic for the Programmer and have done the assignment of Footprint to the single schematic symbols.
Now I have only to create the PCB and then test it.
Here is the Schematic already:
