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

thingiverse

This is a refillable suncream roller based on some nivea suncream roller parts. The nivea suncream roller is a one-way product and not refillable when empty. This design reuses the roller ball and the cap and brings a splittable / refillable design. To get the ball out of the original design: Split the original design with a screwdriver, then you may push the ball out of the original. The get the ball in the new part: Try to be quick! Put the ball on the top of the cap and then quickly push it in. This reduces the likelyhood to crack the plasic. Try to print the upper part with fine resolution. This will make the rolling most smoothly. The design is intended to be printed in upright position without support.
