Small Parts Cylinder

After realising that parts of a product I was designing may be unsuitable for under 3's, I went about searching for a small parts cylinder to purchase. However, living in the UK, I couldn't find a suitable retailer, so I decided to 3D print one instead to test out some of the components designed.

Unfortunately I do not own translucent filament, but it would be ideally printed so that the part can be seen from the side as well as from above!

Edit: Due to being 3D printed, it is beneficial to print it at as small a layer height as possible, so as to reduce the possibility of getting caught on the sides!
