Letter Holder and Organizer

<h4>What's it?</h4> It's a letter holder for envelopes and content that lets you stack letters vertically to save space. It can hold enough space for a year's worth of letters from one person. <h4>Core ideas behind it?</h4> The main goal was to deal with the yearly flood of letters as efficiently as possible: * Store a full letter after reading or not, including the envelope and paper, making it unnecessary to unpack and sort through folders. * Different compartments for different topics like bills, banks, and official documents to cover all regular needs. * Enough space for 1 year's worth of storage, estimated at around 40 letters per year. * As compact as possible to fit in a drawer, so vertical letter storage was necessary. * Only use lightweight 3D printed material, avoiding support structures to keep costs down. <h4>Why this and not others?</h4> That's the tricky part. I couldn't find anything with a compact vertical approach. There were some one-wall-mounted designs (https://www.thingiverse.com/thing:604020) and dozens of single-chamber designs that didn't meet my needs for permanent, sorted, 1-year storage (https://www.thingiverse.com/thing:660493). So the available solutions were pretty far off. <h4>What's the outcome?</h4> In the end, I created my own model after reworking it several times and think it's now "market ready": * Printing time averages around 5 hours with average quality and speed. * Material usage is approximately 55 grams. * It's a tall structure that may warp if not stuck properly to the printing bed. Printing with a raft is recommended. * There are bridges on top, with the longest one being about 15mm long. While it's not a long bridge, make sure your printer can handle it or use support structures instead. * The design is very functional but not the prettiest. Since it'll be stored in a drawer anyway, it doesn't need to look great.
