Clip & block is an open source construction kit (CC By‑SA 4.0). It can create solid structure for electronic projects with a 3D printer. Pieces can be assembly and removed easily for adding and remove components. It is still under development but i will present you my own projects later.

My goal is to make it :

easy to print
easy to extend
be able to carry electronic components

Step 1: Print Your First Clip & Block

Clip & block is easy to print (no support, it's possible to print it in any direction, not to much precision needed, shapes are simple).

To start, clone or download the project locally from GitLab.

First step, you need to print four pieces :

For the two plates :

go to directory stl/basic 
get the file I-3.stl 
get the file I-4.stl.

I-3.stl → letter I is for the shape, number 3 is for number of holes.

For the clip and the blocker :

go to directory stl/clips
get the file blocker-2.stl (lay it flat, there is a function for that in Cura)
get the file clip-2.stl.

number 2 is for the height of the clip (for two pieces). blocker-2.stl will work only with clip-2.stl.

You don't need two much materials for these pieces (2 g and 0,83 m with my settings).
Now, you can assembly pieces ! To unmount, you need to push the blocker from the other side with a small tool.

If it doesn't fit well, you can test other blockers, blocker-2-easy.stl or blocker-2-strong.stl.

You can print other plates to play with it and see that it's strong !

Step 2: Pieces List

In stl/basic directory, there is a big number of pieces (around 75). They are classified by shapes and number of holes (in three dimensions). Here is some samples :

I-3 : I, in length, 3 holes length

LF-3-2 : LF, in L flat, 3 holes length, 2 on the other side

L-2-1-1 : L, in L, 2 holes length, 1 height, 1 width

L-2-2-3 : L, in L, 2 holes length, 2 height, 3 width

U-2-2-2 : in U

P-2-2 : P, Flat

C-2-2-1 : cube, 2 holes length, 2 height, 1 width

IR-3 : IR, in length, rounded (for pieces in rotation)

IHR-3 : IHR, in length, half height, rounded

Step 3: Pieces for Electronic Components

I have create pieces for specific components. They are in the directory stl/electronic.

For example, you can see the two pieces that can include NodeMCU (I love this card :) )

There is a lot of types of this pieces, with more or less holes, only on one side, etc. You can browse it in this folder : clip-and-block/stl/electronic-parts/nodemcu

Here is the list of components that you can find in Clip & block. This list is growing and is not up to date :
