Loop Design Napkin Holder

Hello! This is not for a class but I used things I learned from my CompFab class for this short project so I decided to make an instructable on it as an homage to the class.

I got inspiration from this laser cut design napkin holder by Jonathan_K1906 via Thingiverse, however, I wanted to make a design that would work for 3D printers. I searched up some laser cut patterns and saw this loop design that I really liked so I made a similar structure to Jonathan_K1906's and used the loop design.

I designed this napkin holder to hold napkins of size 6in (or less) width x 6in (or more) height. If you want to know specifically what napkins I used to model, its the Kirkland ones from Costco :).

• Fusion 360
• 3D printer
• Hot water for assembly

Since this design is fairly straightforward, I won't go too much into the detail.

To make the connecting parts:

I hand drew the edges with .5in or .25in joints, then did a simple extrude in one direction.

To make the loops:

I imported an svg image of the loop design into Fusion 360 and hand drew loops based on how they were made in the svg using the "Fit Point Spine" tool. Then I used the "offset" tool and made the loops .25in wide.

After, I extruded the sketch and joined all the bodies together into one for the outer frame.

After printing the separate parts, they actually could not fit together well. I saw this technique online from many sources to put parts in boiling water in order to fit tight parts together and did that.

Random video here showing a method of doing that. Make sure to not burn yourself!
