The original is wonderful, but I noticed a bit of trouble at the escapement end of the world. As built the hook end of the the pallet fork was not well centered on the escape wheel. Also there was potential for interference between the other end of the pallet fork and the impact pin housing.
I have posted updated versions here of the Train Front Frame and Impact Pin Housing that correct this minor (but potentially problematic) misalignment. The Train Front Frame has a boss that has been reduced in height. The Impact Pin Housing now has a chamfer on the leading and trailing edges that should prevent jamming.
My sincere congrats to LarkysPrints for a great desk-toy!
