This is a comprehensive kit package containing both my precision-crafted 20mm T-slot optimized for smooth 3D printing and my expertly designed 3D printed lens holder tailored to fit the 20mm T-slot (inspired by https://www.thingiverse.com/thing:2331488 and https://www.thingiverse.com/thing:2464765). To complete your optical rail system, consider using: [T-slot M4 thread nuts such as these](https://www.amazon.com/CNBTR-European-Standard-Aluminum-Sliding/dp/B01D83H10W/ref=sr_1_3?ie=UTF8&qid=1501694102&sr=8-3&keywords=t-slot+nut+M4) [M4 nuts like these](https://www.amazon.com/Alloy-Steel-Socket-Screws-Black/dp/B017NC2ISY/ref=pd_bxgy_60_img_2?_encoding=UTF8&pd_rd_i=B017NC2ISY&pd_rd_r=ZJ3ZJ55185J8XS63W1AJ&pd_rd_w=estUe&pd_rd_wg=NDFTr&psc=1&refRID=ZJ3ZJ55185J8XS63W1AJ) or [these from a kit with varying lengths](https://www.amazon.com/Hilitchi-210pcs-Stainless-Socket-Assortment/dp/B017N7ZI72/ref=sr_1_7?s=hi&ie=UTF8&qid=1501694219&sr=1-7&keywords=M4+bolt+kit) [These 50mm lenses are perfectly suited](https://www.amazon.com/gp/product/B00BIKGMZ8/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1) The 20mm T-slot and the 50mm lens holders both print exceptionally well, with all parts fitting together seamlessly.
