But the tissue would always get really black and disgusting and so my hands would get all black and disgusting so I made this 3D printed whiteboard eraser that uses tissues to clean the board. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548083666110-5FRSQ9K65M14578134KX/2019_0116_10350400.jpg Engineering - Expo Marker Holder I have PET (pseudo) whiteboards all over my room, and so it’s really annoying to have to go back to where I keep my expo markers every time I need to write on a board, so I made these marker holders for each of the boards, and each holder has a marker in it. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548083733792-Y1HSILJQVE3KZC3NHJ5W/2019_0116_10333000.jpg Engineering - Scrap Paper Dispenser My grandfather used to use these 1/8 pieces of used printer paper as scrap, and I have a lot of extra used printer paper that would otherwise go in the recycling, so I made this dispenser that holds all of these 1/8 pieces of paper. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548083780347-RWR3W33L7BON2RFQ3M52/2018_1204_03023200.jpg Engineering - Smartphone Wall Stand I generally like watching videos on my way to bed, but having to hold up my phone as I’m falling asleep is too much work, so I made this wall stand for my smartphone so I could effortlessly flood my eyes with blue light as I fall asleep. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548083780297-ZHOKUR87QU5X3GG82KLX/2018_1212_22213300.jpg Engineering - Succulent Pot There was an event in which succulents were being given away, so I design this hexagonal succulent pot for mine. It comes in two parts, the top having a hole for water to fall through, and the bottom being a water collector. The two parts have the same hexagonal shape, and the top fits into the bottom section. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548085440099-82J4MPWDQJPS1SZAOUZZ/DSCF4966.JPG Engineering - PET "Whiteboard" Wall Mount My local Barnes and Noble had a big sale on these PET sheets, so I bought a bunch of them and put them all over my wall so I could do math on them with expo markers. I originally used velcro, so I could take them off, but the velcro is stronger than the adhesive so that didn’t work. So I gave up on that idea and used foam mounting tape instead. But now I use these 3D printed pieces that allow the PET to slide out from the top, so I can do math on these mini whiteboards and bring the around my room to another board to continue my work. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548084806536-H4CSCWS5LSLTA3Y03NN9/DSCF4967.JPG Engineering - Calculator Wall Mount I like doing my math on whiteboards on my wall, but having to pick up my calculator every time I need to do a calculation is too much work, so I designed this wall mount and put it up next to my PET (pseudo) whiteboards. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548085381533-K4GTX7KYJSPAPFAPWXEJ/DSCF4979.JPG Engineering - Glasses Holder I lose my glasses a lot, so I figured having a dedicated place to put them would be a good way to not lose them. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548087189538-MLPXGZG505SITILOFQLR/DSCF4982.JPG Engineering - Pen Holder One of my friends designed a 3D printed pen holder, and so I decided to design one for myself. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548087192015-EGM9M2O5WGGYPKGEPD2N/DSCF4985.JPG Engineering -

Clothes Dryer Replacement Knob Someone broke the knob on the clothes dryer and a replacement was $20 so I told my father I would just design and print a new one (this filament was free too so I saved the family a whole $20 ayyyy). https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548104810946-4UKKNJDZTR0MHK3I7TDY/22424306_1930031710548210_430337316328164841_o.jpg Engineering -

So she woke me up early that day and I built it before she left. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548970778560-P85RLNDLE2GV7IF5GCEK/20150909_203527.jpg Engineering - Name Sign We had to make name signs for our English classes in my high school, and my teacher really liked the light up sign I made for myself, so I made him one.

So I went through some electronics recycling bins and found a USB cable, and made this powerbank flashlight. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548128034736-SYMPDOSBAAP2XFUCPC2Z/DSCF5022.JPG Engineering The light switch only turns the lights on in the “on position”, and off in the “off position”. This is so that no matter what state the remote leaves the lights in, the light switch will always work as intended. As shown in the picture, the lights are on while the light switch is in the “off position”. This means that the light switch needs to be flipped twice in order for the lights to go off. https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548097477283-3FCG8VUYKPVVDICC338E/20181027_021830.jpg Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548126942120-HDLZFUH0MRLRVCRO59AT/20180910_190147.jpg Engineering Servo-Based Light Switch Controller https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548127238649-EE7HAFH6US408G6QYP40/20181027_021830.jpg Engineering Wireless Light Switch Module https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548127919854-OA7GBXT433IMKDSU35RQ/DSCF5005.JPG Engineering Wireless Light Switch Remote https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548129228908-VPVZ5MA7TOFG2YEZWFVY/DSCF5002.JPG Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548129862287-NQXTKEO2CA0LJKL9XRNW/DSCF5003.JPG Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548129019735-KY1QDY52UM73NPUYQTOL/DSCF5010.JPG Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548126217485-6T87NCVFVLPW0SVBH63H/DSCF5008.JPG Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548129821770-L7K0YUNDGQSMTNJTLGCQ/DSCF4993.jpg Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548129899861-R4XBUGBPX1PFVUSQJS9A/DSCF5009.JPG Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548104186963-PQ1DTNXU95KCBGAO2NZX/20161018_102046.jpg Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548104186971-BMEETG08QWNJYQK0XP1E/20161023_094916.jpg Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548104187402-89EL822QKPLQQ18OIMQL/20170605_071955.jpg Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1550811491578-SJR8GI76IFT7LXAGHAOT/first+coil+gun+test.PNG Engineering First Coil Gun Test https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1550811471754-4UH3ZO36E8MS4IFX2ZQY/20170530_202546.jpg Engineering Final Version (without cover) https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1550811331390-ELILEXIC5D73MGSIQY44/20170530_202516.jpg Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548126666860-Y7NMQBBMBW16KOB3FTIG/50310003_409691753104070_1936523349865791488_n.png Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548126704912-6D8C7K3P5XFG4CT5H4EB/51052028_1034200983419267_4968701335206625280_n.png Engineering https://images.squarespace-cdn.com/content/v1/5c39b8414611a0b37c9c4aba/1548123907579-P278OBK3KI4VN8DEKPP4/20160820_170701.jpg Engineering -
