Printable TPU o-rings that can be used to assemble the Dum-E handy desk buddy ([https://makerworld.com/en/models/195554#profileId-217277](https://makerworld.com/en/models/195554#profileId-217277)) with permission given by the creator.

These replace the need for cutting/gluing neoprene gaskets as called out in the original BOM. Simply fit the o-rings into place and screw down.

The smallest groove (at the wrist) was too thin and unprintable even with a .2mm nozzle. The underside of the supports also came out too poorly to actually fit anything inside of the groove. The solution for that was was an oversized gasket that purposely doesn't fit in the groove which seems to work well.

If slicing yourself: Print SLOWLY. These are very small and a very quick print that you want to be fairly accurate, the slower the better. I used a .4 nozzle with .08 layer height with .32 line thickness at 1mm/s MVF. YMMV especially depending on which TPU you are using.
