Submarine Bath toy

cults3d

This is a toy Submarine that floats initially then fills with water and sinks to the bottom, as it sinks it moves forward. Good for baths and swimming pools etc. This is a toy that myself and my son have created as his first intro to 3D printing. Infill over 25% Min to achieve neutral buoyancy with most filaments (PLA) Having printed a few of these I have noticed that the buoyancy is affected by different filaments (colours/brand) and infill I have made scaled down versions to test the buoyancy as all filaments are different With some filaments you will need to submerge in the pool/bath first then empty (shake out) the water and then i works, will depend on how hydrophobic your filament is. I haven't tried making one with Matt filament or silk yet - please feel free to add comments on your findings. This has been free on thingiverse for more than 4 years now and i have 500+ Downloads, I am making this a paying stl from now on as i am confident that it is Water tight (pun intended) and lots of people have enjoyed it for free. Over the last 4 years and lots of downloads i have not received one tip. I will add better pics shortly.
