3D Printer

This 3D printer is made primarily of 3D printed parts. It has a modular hot end which can be replaced with any type of head such as a Dremel, a pencil, or a direct extrusion system. *I designed this whole project based on orthographic drawings of parts I found online so I expect there to be some mistakes if it were to be made with real parts. If you notice any problems with the design, please let me know as I will be happy to fix them when I can.* Part list: - Endstop Switch: https://www.aliexpress.com/item/32842008513.html?spm=a2g0o.search0306.0.0.482639f6GhVPfI&algo_pvid=71c0f1d8-fe9d-4c0c-9081-e315553af3df&algo_expid=71c0f1d8-fe9d-4c0c-9081-e315553af3df-17&btsid=0bb0624016036511112067243e0ad9&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ - 2020 Extrusion Inner Corner Bracket https://www.amazon.ca/Corner-Bracket-Aluminum-Extrusion-20x20x17mm/dp/B01L698QOU - Blower Fan https://www.alibaba.com/product-detail/Gdstime-3V-5V-12V-24V-50mm_1932068265.html?spm=a2700.wholesale.deiletai6.17.4739238eRLry98&fullFirstScreen=true - E3D V6 Hot End Full Kit https://www.amazon.ca/Wangdd22-1-75mm-Printer-Extruder-Accessories/dp/B06XBXDJY3 - Bearing for Extruder Motor https://www.bearingscanada.com/10x15-Bearing-6700ZZ-10x15x4-Shielded-p/rcb10x15-1.htm - Extruder Pulley with Teeth https://www.aliexpress.com/item/10000355974687.html?src=google&albch=shopping&acnt=494-037-6276&isdl=y&slnk=&plac=&mtctp=&albbt=Google_7_shopping&aff_platform=google&aff_short_key=UneMJZVf&&albagn=888888&albcp=7386552844&albag=80241711349&trgt=743612850714&crea=en10000355974687&netw=u&device=c&albpg=743612850714&albpd=en10000355974687&gclid=CjwKCAiA-f78BRBbEiwATKRRBGndOsKzMFr1ebGAPGruyFnr4FTmpEeMnQ6Ou7jKvckVBp80zh6gQhoCws4QAvD_BwE&gclsrc=aw.ds - F623ZZ Bearing for Belt https://www.banggood.com/10pcs-F623ZZ-Flange-Bushing-Ball-Bearings-3x10x4mm-Miniature-Deep-Groove-Flange-Ball-Bearing-p-1065370.html?p=9X051049165582016063&cur_warehouse=CN - Inductive Proximity Sensor (Distance Sensor for Calibr
