About this 3D model

My Wade extruders are now under fire since over one year and still doing great. The most used one now has some noticeable slackness and I need to soon replace the gears. I decided to make a bit more beautiful gears with a beefed-up teeth-area. This is the result... enjoy! Tech data: 11 x 39 teeth-ratio Bore on small pully is made for Ø 5mm motor axle and has space for 3 M3 set screws (press in M3 nuts...)
