This is a scaled down version of the fantastic beer keg model produced by The_Hunter (available here: https://makerworld.com/en/models/575108#profileId-497200).

All I have done is divide the HO scale by the N scale: (87.1 / 148) ≈ 0.589, converted to percentage (58.9%) and scaled the model down. Would reccomend printing using a 0.2 nozzle.
