Education Lock and Pins - Resized - More Pins

thingiverse

This is a remix of FrenchKey_fr's education lock and pins. I have added a lip to the bottom of the lock body to prevent the core from falling out of the back. I also added two tabs for applying tension to the core. The body bible (spring area) has been shortened to use a smaller spring and lower print time and material usage. Bevels have been added to all pins to match industry standard design. This version contains serrated, T, mushroom, spool, and standard driver pins (the top pins) and two lengths of key pins (the bottom pins). Use the 20mm key pin for all drivers except the T-pin, which should use the 26mm key pin. All parts are printed at 100% scale and have proper clearances to allow smooth turning and sliding <b>without any need for sanding or scraping</b>. The back of the lock body, where the core sits, is mostly empty to prevent excess friction on the core when turning. This design uses a 10mm x 35mm spring from the local hardware store (cost about $0.70). Any 10mm wide spring with an appropriate length will work. <b>Don't forget to post Makes! I love to see how things come out on different printers and colors.</b>
