HO Train wheel gauge
cults3d
Wheel gauge for HO Model Trains. HO standard wheel base is 14.4 mm. A smaller offset will make the train derail so I came with this design to properly align all your train wheels. One part has a bigger grove in order to fit the free wheel (the one with the plastic insert) Not all the printers are 100% accurate so I recommend you try 98% 100% 102% if your print is not correctly scaled.
