I will present here a pcb holder. I was not not intend to present it ,but i will do it because i was looking to buy a pcb holder and and i was amazed about the prices that i found! Just some pieces from plastic and metal costs around 50 euros!! I have not understand yet ,why this thing is sooo expensive! . So .i would like to give some thought to people that intend to do something like that . There are many ways to make it,just use your imaginatioan and you ‘ll do it. Do not try to make exactly like mine, you may don’t have exactly the stuff i use, you may have something else in your drawer, i am just trying here to give you the base idea here and push your imagination.
The base is on a piece of wood and i screw up a ball bearing drawer slide. I cut two pieces of aluminium as the vertical column that will be handed the pcb
i tried different combination as below
But nothing works. For a stable column,it must be screw up both sides
Now, let’s go to the other column with the spring on the top. Just look the photos
Next step is how to hold the pcb. A nice way is with those 
But i found another better one. Those small pieces of hard rubber, i place two on each side
The left side is the stable. The right side is the spring. But both are capable to turn around
Now , the final step , i should find a way to stop and the rail at a specific point ,depend each time at the size of the pcb .So i did a guide with 13 holes. It’s up the size of the pcb each time ,to choose the right hole and stable the rail at the right point.
There is a fork on the rail , and along with a metal pin with stable the rail
