Filament Drying Box Monitoring System

Final Project Done: This project was my first hardware Project to begin with, it taught me a lot of things how does wiring works, raspberry pi machine pin codes and stuff.

I agree on the fact that its not polished for display but the main points it works which is important. I tested it for PLA, PLA+, TPU and it worked for most of them . I left them dry inside the box and cooling system worked. While I agree I should have designed the much better built for stands and stuff but it works which is pretty important I think for project like these. IT is not stylish as hackpad or drone since it was an techincal experiment and stuff. And used many of the pieces.

Things To Add in Future.

I would probably make a better stand for this, a proper attachment for this and enclosure and take many things in account for printing dimension and stuff

Worked on electronics and breadboard verification for electronic schema Uses a DHT11 Humidity Sensor, OLED O 96 module, Raspberry PI PICO. DC BRUSHLESS FAN for moisture monitoring(which i am still working on to specify which one is better). __________________________________________________________Schematics is fine ( its good it doesn’t need a custom PCB a regular breadboard, but problem is during assembling we have to map things out since my enclosure tub has a vertical cutout for the screen unlike the breadboard which horizontally attached to the screen. __________________________________________________________ The major stuff needed is assembly, the screen updating based on the sensor which currently it does.

Here are Some New Changes made: The orignal electronic enclosure design failed because of the two flaws first one it covering half of 608 bearings. To fix that made some design changes but then space for PI would decrease. So i made a new lid on the one with 4 pillars for electornic enclosure which is a independent box on its own with ample amount fo space for PI and Humidity sensors. In terms of schematics they is really not anything since very basic stuff such as wiring managemnt for sensor and some ventilation holes which need to be made. The following are already 3d printed: SPOOLER_BASE, ENCLOSURE_LID. only the ENCLOSURE ITSELF IS LEFT since I need to double check some PI and OLED screen issue in order to send for 3D printing. Really can’t waste filament . So imported STL files for PI PICO , OLED o 96 to check out somethings. But the Project build is 75% finished around

01 Spooler Base is Done 3D printing filament (especially PLA like your Inland spool) acts like a sponge for moisture in the air. When it absorbs water, it causes brittle filament, bubbles, and terrible print quality. By putting this base plate inside a sealed Tupperware or airtight cereal container with some packets of desiccant (silica gel), you create a “Drybox” that keeps the plastic perfectly dry. Furthermore it made for Inland Spool and helps reduce waste reduction
