HO Broadway Limited GG1 Drive Gear

cults3d

This is a replacement drive gear for an older Broadway Limited GG1 locomotive. The parts dealer at BLI told me they no longer make or carry this part, or any parts for this model, so I decided to make my own and share it. You will have to print this with an SLA (or a fine metal) printer using Siraya Tech Blue resin as it is one of the toughest resins on the market and the gear requires a press fit and has to withstand a lot of ware and pressures. YOU ALSO NEED a Number 32 or 33 drill bit to clear the hole for the press fit (No. 33 is smaller). No. 33 is .114", and No. 32 is .116", The drive axel is .119" https://siraya.tech/collections/united-states/products/blu-by-siraya-tech-for-lcd-resin-printers-1kg
