Napkin Holder - Adjustable size

Introduction

This holder is designed to hold paper napkins that I got at Dollarama. These are about 160mm square. The holder will twist to hold napkins tightly. You print two bottom and two top pieces. The bottom pieces determine how many napkins can be held and I provide two sizes. A 40mm and a 30mm opening. Print two of the same size. 

Printing instructions:

You can print at any layer height from 0.3 & smaller. The smaller, the smoother the surface.

You should paint the seams so they are next to the napkins and not visible. 

I used 20% infill, rectangular, 3 perimeters and at least 3 top/bottom walls. 

The model shown was printed in PETG but PLA will work fine.

Print all models with the horizontal piece on the floor. Because of layer lines, ensure you have good adhesion between layers as the columns are built. (use max nozzle temp for your filament that will work and still give a good model)
