Hub cap for Rinner wheel drum

Simple replacement hub cap for a Rinner wheel drum with an inner diameter of 81.5mm for the cap. I used M4 screws for two reasons:

• make sure it doesn't fall apart in case layers crack
• to prevent the cap from dropping out too easy

Add the screws after plugging the cap in. The screws displace the plastic a little and squeeze it against the inner wall of the wheel drum.
