I was reminded of the rather nice drawing of a set of coal scales in Roy Link's superb Crowsnest Chronicles book and while I can't match his version with lots of beautifully panto-graph milled pieces I thought I'd have a go at modelling it up in CAD to 3D print. As this model is in 16mm:1ft scale it took a while to print (a little over 5 hours) at .03mm layer height on my Phrozen Sonic mini 4K. I printed double of some of the smaller pieces just in case there were issues.

The first attempt has actually assembled into something that looks pretty good first time.  Sorry for the dust in the photo, I have sanded off the support structure and also lightly add a grain texture to the timber of the trolley.

I'm looking forward to painting it now.
