Designing 3D printed attachments for the Micromelon rover is a fantastic way to upskill in CAD design while making your own custom additions. Tinkercad is a free-to-use software that allows you to bend and stretch existing shapes to create your own ones. In this guide, we’ll be going through some of the basic Tinkercad tools and how we would go about designing a sumo ramp for the rover.

## The Workspace:

|
||||
To get started, first download our rover shell clip [here](/s/MM-Attachment-Clip.stl). Next, open up the downloaded file in a new Tinkercad project by using **Import > Choose a File > (open the file) > Import**. Drop a ruler into the workplane and rotate the clip so that it looks like the image below:
|
||||
|
||||
|
||||
|
||||
|
||||
#### Step 2:
|
||||
|
||||
Next, use a rectangle to cut off the bolt tabs at the front. The hole should look like the following image before grouping.
|
||||
|
||||
|
||||
|
||||
|
||||
#### Step 3:
|
||||
|
||||
Next, we need to make the weapon for our attachment. For this, we used a wedge and modified the shape so it serves as a sumo ramp. It’s not attached to the clip just yet.
|
||||
|
||||
|
||||
|
||||
|
||||
#### Step 4:
|
||||
|
||||
Next, we need to attach the ramp to the attachment clip. Move the ramp in so that it’s overlapping with the clip. Make sure it doesn’t come too far in as the rover needs to sit inside the clip. Use the align tool to make sure the ramp is centred on the clip. Don’t worry about the ultrasonic sensor opening, we’ll take care of this in the next step. Group the objects together once everything is in place.
|
||||
|
||||
|
||||
|
||||
|
||||
#### Step 5:
|
||||
|
||||
Finally, we need to cut a hole so that the rover ultrasonic sensor can see through the ramp. Download the [Ultrasonic Bore](/s/Ultrasonic-Bore.stl), and import it into the workplane. Next, position the bore as a hole so that it can cut through the hole on the clip and into the wedge. It’s easier to look from the back of the clip. The align tool and looking from many directions can help a lot with this step. Once everything is in position, merge the objects so the hole cuts through.

#### Complete:

|
||||
|
||||
|
||||
|
||||
Now that is the complete design on how to make a very basic attachment for the rover. Try experimenting with more complex shapes using a combination of solids. Maybe try to increase the amount of contact your shapes have with the rover clip to make a stronger bond.
