Here are some guidelines to keep in mind when designing your Space Container. We

under-stand that making a 3D model is tough for beginners! We encourage participation first and foremost, so don’t forget that a great Space Container Idea is worth more points during judg-ing than an expertly crafted 3D model. (But havjudg-ing both will score big!) You won’t be disqalified if you submit a model that doesn’t comply with every guideline below, so if you’re a beginner

don’t fret if this seems overwhelming. Before you know it you’ll be a pro!

does it have to be 100% 3d printable Or JUST A PART OF IT?

The main structure of the container needs to be 3D printable, if not all of it.

We will allow the following exemptions for living containers (plants, bugs, etc.):

we will allow the following exemptions for all containers:

You may use a velcro. Because astronauts love velcro. You may use plexiglass or plastic baggies for windows.

THIS IS A SPACE SPECIFIC GUIDELINE!

Maximum Space Container Dimen-sions are 5cm wide x 10cm long x 5cm tall (about 2in x 4in x 2in) the space print volume, it will be judged as if it

were scaled down to fit this volume.

THIS IS A SPACE SPECIFIC GUIDELINE! Please don’t include unsupported, hanging geometry in your design.. The maximum overhang angle is 45

de-grees. (Refer to next example.)

THIS IS A SPACE SPECIFIC GUIDELINE! You can only build outward from the lay-ers below at a maximum recommmend-ed overhang angle of 45 degrees. This will not require removable supports. THIS IS A SPACE SPECIFIC GUIDELINE! DO NOT create removable supports of any kind! This is one of the differences with 3D printing in space. Floating de-bris that breaks away is dangerous and

could be inhaled by the astronauts.

THIS IS A SPACE SPECIFIC GUIDELINE! Assemblies that are created in print are allowed and welcome. Small Internal supports ARE NOT ALLOWED in space,

as they can create floating debris.

THIS IS A SPACE SPECIFIC GUIDELINE! Multi-part assemblies are allowed. All parts must fit into ONE 3D print session - max 5cm x 10cm x 5cm print volume.

Minimum recommended wall thick-ness is 1mm.

Most consumer 3D printers can bridge material. The maximum recommended

bridge distance is 10mm.

It is generally advised that support structures have a height to width

aspect ratio of 4:1 or less.

Your 3D model should be solid geom-etry. For example, the model on the right has no top surface and zero wall thickness. This is not a 3D printable model. If in doubt, upload your model

to Meshmixer to analyze your STL file

No shared single edges (lines) like above. If you have mulitple parts to print at the same time, make sure there is at least 1mm of spacing between the parts.

Slip fit guidelines are: .5mm on every

side. (1 mm diameter difference if an axle) Snap fit guidelines are: .2mm on every side (.4mm diameter difference

if an axle).

A part that is designed to rotate or slide within another part.

Avoid big, thin flats because they may tend to warp.

A part that is designed to press or snap into another part and does not move.

Maximum STL File size is 20MB. STL files are mesh geometry (triangles). A simple box may be a few KB, whereas a complex model that requires a mesh with more triangles will be a larger file. We encourage advanced designs and have given you a large file size limit!

Complex Mesh

Moderate Mesh

Avoid pointed or rounded bases. If a base is needed, opt for a mouse ear base or a base plate instead. More sur-face on the print bed is advised for a

more stable design.

For example, this mesh is complex, but is under 20MB if exported proper-ly. Chord Tolerance or Angular Control can be modified in some 3D software packages to change the resolution of your STL file export. Otherwise, in Meshmixer you can upload your STL file and re-export it using the STL

Bina-ry Format to reduce file size.

Just a reminder that we reserve the right to tweak, edit, or re-create all

submissions for our program needs - i.e. make sure its perfect to print in space or here on Earth. It’s in our Official Rules, but we wanted to say

it again!
