Remix of "Crack The Code" Safe Puzzle Box from DIY

<p>I found the “Crack The Code” Safe Puzzle Box on DIY's website but it was designed for a laser cutter. I don't have access to a laser so I thought I would redesign it for 3D printing. I kept to the original design as much as possible with the exception of the safe door design. The original design used pins to hold the door in place (and swivel open) but &nbsp;I wanted something a bit stronger so I used a metal rod to hold the door in place. I purchased the parts, as listed on DIY site, from Amazon (except for the ribbon cable and screws which I already had laying around). All sides of the safe fit together nicely, so the only glue I used was some hot glue for wire management (on the safe door and cable routing). CAUTION: You might want to use defused LEDs. I used normal ones and they are extremely bright.</p><p>Arduino UNO Rev3: <a href="https://www.amazon.com/gp/product/B008GRTSV6/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&amp;psc=1">Amazon.com: Arduino UNO REV3 [A000066] : Electronics</a></p><p>0.96" OLED Module: <a href="https://www.amazon.com/gp/product/B072Q2X2LL/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&amp;psc=1">Amazon.com: UCTRONICS 0.96 Inch OLED Module 12864 128x64 Yellow Blue SSD1306 Driver I2C Serial Self-Luminous Display Board for Arduino Raspberry Pi Pico : Electronics</a></p><p>360 Rotary Encoder Switch: <a href="https://www.amazon.com/gp/product/B07R8DP2BN/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&amp;psc=1">Amazon.com: uxcell 360 Degree Rotary Encoder Code Switch Digital Potentiometer EC11 5 Pins 20mm D-Shaft 10pcs : Industrial &amp; Scientific</a></p><p>Variety of LEDs: <a href="https://www.amazon.com/gp/product/B093GL1FFH/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&amp;psc=1">EEEEE (20 Types) 301 pcs Long Lead 5mm LED kit and LED diode Lights Emitting Diode LED Assortment Kit for Tiny Small led and Single led Light arduino led 5mm led Lights led diode Lights diode led: Amazon.com: Industrial &amp; Scientific</a></p><p>9V Battery Clip: <a href="https://www.amazon.com/gp/product/B07Q21F5XY/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&amp;psc=1">Amazon.com: 20 Pack 9 V Battery Clip Connector Long Cable Connection Hard Shell Black Red Connector (I Type) : Electronics</a></p><p>Several 3mm screws to hold the Uno to the divider and the back plate to the box.</p><p>Metal rod: OD 2.4mm</p>
