Expandable A4 Tray

thingiverse

I designed this expandable A4 tray specifically for printing as many sheets as one requires. The compact nature of this model demands that users assess their own needs and confirm that their printer can accommodate print sizes up to their desired preference. I opted for a size capable of containing standard A4 files, measuring 350mm x 250mm, while the height remains adjustable based on individual requirements, with mine standing at 150mm. To achieve a satisfactory outcome, I employed a 20% infill and 0.2mm layer thickness during printing. For optimal results when printing A4 sizes, I recommend using a larger support material, such as 0.6mm, which facilitates easier removal of the support structure. However, one area for potential improvement in future versions lies in the tray connection mechanism, which can be slightly tight and may benefit from refinement.
