The Öttbrett is a toy for guinea pigs. I built it for a friend.
Excuse my bad English.
Step 1: Material:
2 boards (40x40cm)
Small boards (size after choice)
3.5 cm; 0,3 cm; 0,4 cm; for deepening
Step 2: Step 1: the Moving Parts
Paint upon the small boards the parts which can be moved later
by the guinea pigs.
I have taken a drop shape, but you can also take other forms.
Saw out this.
Step 3: Step 2: Drill Holes
Distribute the drops on one of the boards and mark the drill holes.
Bore then with 3,5 cm of drill holes in the big board.
Loop the edges of the bores and glue both board on each other.
Step 4: Step 3: Drill More Holes
Bore with the 0,4 cm thick drill holes in the tips of the drops. Drill according with this drill which makes thus deepening (I don’t know the word).
Then put them over the big holes on the board. Pay attention to the fact that these are completely covered. Mark to you the bores on the board and bore this with 0,3 cm of drill. Be careful, not to drill too deep.
Step 5: Step 4: Loop
Loop everything carefully.
Pay attention that the edges are completely smooth,
so that the guinea pigs cannot injure themselves.
Step 6: Step 5: the Assembly
Screw the drops on the board. Pay attention that the drops can move.
Now you can hide small little treats for the guinea pigs in the holes.
The guinea pigs will be able to shift the drops with their nose and come thus to the delicacies.
