Refillable sun cream / sunscreen roller (using NIVEA roller parts)

thingiverse

This refillable suncream roller draws inspiration from Nivea's suncream roller components. Unlike Nivea's one-way product, this design allows for refilling once empty by repurposing the roller ball and cap. The innovative feature includes a splittable/refillable design. To disassemble the original roller: Utilize a screwdriver to separate the parts, then carefully push the ball out of its housing. For reassembly, act swiftly! Place the ball on top of the cap and quickly push it inwards. This method reduces the likelihood of damaging the plastic. When printing this design, use high-resolution settings for the upper part to ensure smooth rolling performance. This design is intended for upright printing without support.
