Pull the piece indicated by the arrow upwards by making a valley-fold over the purple line.

Step 2:
Make a valley-fold over these 4 lines.

Step 4:
Make these folds from the edge of the model to the center, not any further. First, make 2 valley-folds below, on the right. Then, make 2 mountain-folds in the middle. And make 2 valley-folds on the top left.

Step 3:
Turn the model.

Step 10:
Press the edges indicated by the arrows flat from above.

Step 8:
Unfold the folds of step 7

Step 9:
Pull the edge indicated by the arrow downwards by making a valley-fold over the purple line.

Step 7:

Step 16:
Repeat step 13 to 15 on the other 3 same triangular pieces of the model.

Step 15:
Push the 2 ends indicated by the arrows towards each other again, in the direction of these arrows.

Step 12:
Repeat steps 6 to 11 on the other 3 flaps

Step 11:
Fold the triangular piece below the purple line upwards by making a valley-fold over this purple line.

Step 14:
Fold the triangular piece above the purple line to the inside of the model by making a mountain-fold over this line.

Step 13:
Pull the ends at the bottom of the 2 arrows outwards, in the direction of these arrows.

Step 21:
Repeat steps 17 to 20 on the other 3 same places of the model.

Step 19:
Make a valley-fold over these lines, everything is already prefolded.

Step 20:
Now you've made an extra end. Fold the end upwards by making a valley-fold over this line.

Step 18:
Pull the upper layer of paper loose from the rest of the model at the places indicated by the arrows.

Step 17:
Push the pieces on the left and right of the purple line upwards by making a valley-fold over this line.

Step 22:
Pull the corner indicated by the arrow upwards by making a valley-fold over this line.

Step 28:
Make the same folds as in step 27 on the ends indicated  by the 2 larger arrows. Fold the edge indicated by the upper smaller arrow to the same height as the smaller arrow below. Fold the end on the left also to the same height.

Step 25:
Fold the 2 upper ends downwards over this line.

Step 26:
Valley-fold over these 2 lines.

Step 24:
Repeat step 22 and 23 on the backside of the model. Make sure that the model gets an equal amount of flaps  on the left and right. Then turn the model, so a brighter side of the model is upwards.

Step 23:
Press the corner flat from above, see arrow.

Step 29:
Turn the model.

Step 27:
Mountain-fold over the line below and valley-fold over the upper line. Make the same folds on the backside of the end. You actually just push the end downwards when you make these folds.
Do the same on the end at the left.

Step 30:
Make the same folds as in step 27 and 28 on this end, see arrow.

Step 31:
Make an outside reverse fold over these short lines.

Step 32:
Pull the tip indicated by the arrow to the inside  of the model by making an inside reverse fold over these lines.

Step 33:
And push this corner to the inside by making an inside reverse fold over these short lines.

Step 35:
Turn the model.

Step 34:
Press the edges indicated by the arrows inwards.

Step 36:
Press the leg flat from aside by making a valley-fold over this line. Do the same on the other 5 legs.

Step 37:
Push the tip of each leg upwards a little by making valley-folds over these very short lines.

Step 38:
Valley-fold over this line. Fold the tip indicated by the arrow below to the spot indicated by the upper arrow. Then, turn the model.
