Materials:
A box of discs.
The expansion bolt shield (d = 1 cm) with a nail bent 90 degrees (d = 0.5 cm).
Instruments:
Awl
Jigsaw
Drill with a drill.
1. We take a box from under the disks and measure out 5 cm from the top.
2. Draw a straight line around the circumference of the box.
3. Saw a jigsaw along the line.
4. We take a drill with a drill d = 0.6 cm and drill a hole.
6. We take an awl and pierce a hole (d = 0.3 cm) around the circumference of the box. The distance between the holes should be at least 0.5 cm. Holes need to be pierced from the outside.
7. We process the side of the skin (where the cut was made).
Well, that's almost done. We made holes with an awl so that the hamster does not slip when it runs.
It remains to collect everything.
It turned out pretty not bad.
