Last crawled date: 4 years, 5 months ago
Heavy duty spur gear
Module = 3 mm
Number of teeth (z) = 16
Tooth design from http://hessmer.org/gears/InvoluteSpurGearBuilder.html
It endures big projects. Didn't make a keyhole because enough pressure on the screw will hold and delivers torque. Loose hole for M4 and tight hole for M5. It can be reopened with a drill to get bigger diameter (6 loop count on vertical shell).
If you scale you'll change the module. Cut it short in width if necessary.
22g of PLA
19g for ABS
Use rafts for better first layer on the teeth
dxf file with tooth shape is in the pack
step file to change hole (keyhole eg) is also in the pack
