SDTA D-Tool

For those with SDTA D size tubes you'll find that a pin wrench doesn't always work when mounted.

I've always printed solid with PLA+ but you may be able to get away with 50% infill and the top 15-20 layers solid.

Sketchup doesn't do chamfered edges very well at this scale so if printed solid - feel free to sand the edges so it's a little easier on your fingers.
