Drill Press PCB (reverse)

The realization requires some mechanical parts:

- Spring size length 27mm diameter 18mm spring thickness 1.7mm

- 1 full tube (I recommend aluminium) diameter 10 mm

- 1 empty tube (I recommend aluminum) external diameter 12mm and internal empty diameter 10mm

The first tube must slide into the second - I used some technical grease.

Realization :

1 - cut two pieces of 53 mm long full tube to insert into the molded base (use a small hammer to insert them all the way in)

2 - insert the spring in the center of the base

3 - Fix the base on a plane

4 - cut two 38mm hollow tube parts to insert into the printed PCB board (use a small hammer to insert them all the way in)

5 - remember to grease the parts of the pipes in contact with grease!

6 - adjust the fixed drill so that the bit used is 2 mm below the surface.

In case the spring is not very strong, raise it using the clip.stl file

Usage: The drill is on a fixed structure. As shown in the photo, I used a wooden structure and fixed the drill using: https://www.thingiverse.com/thing:1761641/files

Press the base, insert the PCB, activate the drill, when the base is released, it will be drilled. https://www.youtube.com/shorts/7N4cEw7Yr7U
