USO's exist... Unidentified Storage Object's (with an outer disk section that rotates) have started invading build plates all around the world!
The images provided are proof USO's exist...
This is fun and practical storage solution in the shape of a UFO. The USO disk is made of two parts (upper and lower) and link together to rotate around the central body part. Use a light (silicone) lubricant on all the contacting surfaces to ensure your USO disk rotates freely and threads run smoothly together / apart.
A fully assembled a USO printed at standard scale is approx. 125mm in diameter and 75mm in height. Make one just as a fun model UFO or use it as a novel storage container for all sorts of small things. There are seven (7) storage areas inside the USO, one of which is a 'secret chamber' underneath (the screw in base part is hollow). However, unless you know better, to a casual observer seeing the USO on a shelf / desk, they would think it was just a model... and not suspect anything is stored inside.
The USO design is made five (5) parts. One of each part is required. They are easy PLA prints 'without support' on precise, well set up machines. Accuracy is essential so the threads that hold parts together form well and clearances are adequate but not excessive.
Note: An alternative Top has been added which has two small holes in it so the USO can be easily hung up and displayed. The alternative Top file is named 'hang top.stl'
Make a USO as a fun model / display thing or to use for storage. USO's will look great in all sorts of colours. You can also pause your machine mid print (at approx. 1mm height...so very early in the print) to add a coloured ring around the upper disk for a spacey effect. The base looks good printed in a different colour from the body and disk parts (refer images).
Scaling up / down should be okay but do not scale down too far or the clearances will reduce too much to the extent that the parts will not fit together and threads not screw together.
Please refer to the images and print instructions for additional information... and post images of your USO's for other members to see!
