It's been a while since I posted any 3D prints, so heres something I squirted earlier...
I was looking at the lathe tool setting devices from Edge Technology and of course, anything that can be machined in alloy can be printed in plastic

Before making a start I did a search to see if anyone else had done one. This popped up on Thingyverse, it's a useful starting point.
https://www.thingiverse.com/thing:1010033I loaded the IGS file and looked round to see what parts I had to hand. Inline skate bearings, a cheap plastic level that came with a set of Bosch drills. I actually scored 3 vials in the level, but opted to use the 25mm x 10mm one. This didn't match the one used in the 3D model I just downloaded. A bit of time in Rhino got me a useable model that would also make use of my bearing.

I output the model as an STL file to Simplfy3D (use whatever slicer) to configure the print as i wanted it and orient parts. The slicer also added some internal support for the print, shown in grey.

Off to the printer for a couple of hours, whilst the dog gets a walk and we make tea.

The printed parts and other bits ready for assembly, well... just push them together really. The body needed the 5mm hole tapping to take a bolt I had earlier polished flat on a diamond stone.

Here is the first test of the components together, I need to set the screw with nail varnish and probably glue the plug in too with varnish. The vial is a firm push fit so no worries over that falling out or getting out of alignment. It's just resting on the shank of an 8mm drill for now, I will make a proper shaft for it to go on later. Other than the print time it was pretty much a couple of hours work and hopefully a useful tool for the lathes.
