Girder bridge in N scale

My first attempt at printing an 80' girder bridge in N scale came out fairly respectable. A couple of the edges near the ends didn't print perfectly. May have overcrowded the build plate or not raised the objects high enough off the build plate. Still lots to learn about printing but this is a game changer. I recently purchased 2 80' Micro Engineering girder bridge kits. I've assembled one. Not sure I'm gonna bother building the other as the I prefer the printed one more and it's WAY WAY simpler to push a couple keys and walk away! These took 95 minutes to print. Another 20 to clean. Tossed them in a Ziploc bag of alcohol and walked away to do other things. I could get used to this...

This is my 3rd print after a handful of calibration tests. This design was found on thingaverse. So much available for modelers. Found a cool sasquatch design (to me anyway) and printed it last night. It came out 90%. Tweaked some things on the supports to see if I can get it to 100%. Coolest part of resin printing is it takes as long to print 50 big foots or bridges at one time as it does 1.
 
Images of my test projects. Also forgot that I'd lost a pivot block for a Tortoise switch machine. Took me about 30 mins to design one and then send it to the printer. Fits a little to tightly but that was the goal as I wanted to be able to file or sand lightly to get the correct fit. I only needed one so if anyone lost or broke one, hit me up. I've got some extras now.
