380mm Lazy Susan Printed on a 220mm Bed!!

One of my key design strategies is breaking everything down into small design challenges and in doing so even the biggest project becomes tackleable. When I first created my Lazy Susan mechanisms I wanted one bigger than my print bed allowed but that seemed too challenging so I ended up settling for 330mm diameter on my 350mm bed. Simply designing the mechanism became my focus – the challenge. But now that I have a working mechanism the idea of making a mechanism larger than my print bed started to seem tackleable. Someone asked me for a 380mm version, and here it is.

This 380mm diameter lazy Susan can be printed on a 220mm print bed! I feel that is pretty awesome. It feeds my confidence to tackle more challenges like this and opens the door for designs I could not imagine before.

The Design

To achieve this design, I created a second layer to the top and bottom of the Lazy Susan concept. These new layers become the mounting frame for the inner layer (the Lazy Susan layer). Then with all rings quartered and offset 45 degrees from each other, the frames hold the inner layer in place.

With these additional mounting layers the original design height of 9mm increases to 11.4mm which is still quite thin all things considered.

The pin carriers are also in quarters but do not connect. They simply float around inside the Lazy Susan and push each other around as needed.

Printing

A minimum bed size of 220mm x 220mm is required to print these parts.

I have tried to make my main print settings visible on the Cura screenshot but in case they are difficult to read I have summarized them again here…

Material: I choose to use PETG for its durability and flexibility.

My Setup:
Nozzle = 0.4mm

My Settings:
Layer height = 0.2mm
Line width = 0.45mm
Wall count = 4 (1.6mm)
Infill = 40%

Support:
Designed to print without support. Do not add support.

Print Orientation: As shown in the screenshot(s).

Assembly Notes

This design requires no fasteners, hardware or adhesives. But I do recommend adding a very thin layer of synthetic lubricant.

Try to insert the pins into the pin carrier from the bottom (print-bed side). And, keep the bottom (print-bed side) of the assembled carrier downward in the completed assembly.

When assembling the final quarter of the top or bottom assembly, you will not be able to slide in the part completely. The final portion should snap into the mounting portion of the assembly.

Future

I think I have just about exhausted the whole Lazy Susan thing but there is one more gigantic design I may tackle one day. I want to make a Lazy Susan that is about 1.25m (~4ft) in diameter for my crawl space. I have space but it is awkward to access so making an enormous Lazy Susan would be the perfect solution to store more and keep it accessible. In that case, I would have to print the circumference in 12 or 16 pieces (I am guessing). And, that would bring some more challenges.

Where to Get My STL Files

I am now posting all of my new designs on Thangs.com and plan to continue to do so for the foreseeable future. Some of my older designs may not have been migrated over yet so if they are not available on Thangs.com please check on Thingiverse.

Use, Licensing, Comments and Feedback

My primary distribution site for my design files is Thangs.com. Thangs.com is, in my opinion, leading the way in promoting designers and competition amongst designers which in turn fuels the growth of high-quality 3d printable designs for the benefit of our entire community. However, as a result, some of my designs are only available for free for 1 week from when first posted, so please download them when you see a new file available that you are interested in. Also, please like and save to help me with the competitions.

I do not permit the use of my designs for commercial purposes (i.e. you can not sell my design(s) or products printed from my design(s)) without first acquiring a commercial license from me. On Thangs.com I offer membership accounts for access to all my design files as well as a membership for commercial licensing which allows subscribers to sell printed products using my designs.

I welcome comments and feedback as we as requests for customization of designs. I will do my best to accommodate those requests.
