Raspberry Pi Mounting Platform and Bracket

Introduction

This is a 3D printed project to solve some mounting problems with the Raspberry Pi and some associated components. I am planing to use it in a variety of projects.

• I love the combination of a Raspberry Pi but how to mount them?
• I have a project that needs a small voltage regulator and USB slot. I can get them as modules, but how to mount them?
• One project is for a very humid environment, so how to I protect the electronics? ( My solution is to mount them in a jar, but how do I do that? )

What I have designed is a platform that mounts on the top ( or actually on the bottom ) that holds the additional modules, and additionally has a bracket to mount the whole thing "standing up" so it can be mounted to the lid of a jar.

The design is intended to let you customize it to suit your particular needs:

• I am distributing it as Freecad source files so you can modify or add anything.
• Some parts are parametric so you can change some dimensions from a spreadsheet.
• The design is in parts so you can select which of the parts you want to print.

Using the Design

Customize

Unless you are doing a project just like the design is setup for you will probably need to make at least some modifications.

How to Print

• Select the parts you want to print. Normally this will include

and optionally one of

Normally I make the entire model invisible () and then make visible ( in the model view point to the part and click the space bar ) only the parts I want to print. Then you need to also select the parts. I do this in the model view where I click on the parts I just made visible, click on the first, control click on the rest, you can see the parts selected i the 3D view.

Now create a fusion of all the parts (). This gives your model a new part the fusion

When you have the fusion, the whole thing that will print, you need to get it in stl format to feed your slicer. Select the fusion, and create a mesh ( Mesh Design Workbench -> Meshes -> Create Mesh from Shape -> <Standard> - <OK> ) Again this creates a new part the fusion ( meshed ).

My meshed parts have often had defects that create problems in printing. FreeCad has some tools for fixing them. Run them to be safe:

Now select the fusion ( meshed ) and use ( Any Workbench -> File -> Export ...name the file and select stl as the type ) This is the file you need to slice.
