prusaprinters

<p>This is a gear I designed (from step drawing from mcmaster car partfor the TATRA 813 RC project.</p> <p>The Total mounting depth for The TATRA project from shaft centre to shaft centre needs to be 23.5mm according to my measurements.</p> <p>Subtracting the shaft diameter 6mm leaves you with 17.5mm excluding gear lash.</p> <p>This gear is designed so you have enough material around m3 nuts for grub screws. So I change drawing file so that it prints as 15.7mm and then I add a 1.5mm thick washer behind gear.</p> <p>It would make NO sense printing my attached STL file.</p> <p>I have specifically added the fusion 360 file so you can print and experiment.</p> <p>I am currently printing in Nylon.</p> <p>I have NOT tested this gear apart from fitting in swing axle and testing lash.</p> <p>I am posting it here if someone else also wants to experiment.</p> <p>I am printing at 0.12mm layer height</p> <p>nylon</p> <p>hotend 250C</p> <p>bed 60C</p> <p>The grey and black ones in image is some PLA ones I printed for testing.</p> Category: R/C Vehicles
