This is a test tube holder that is adapted for the gridfinity system. Grid spacing is 3x3. The holder can hold 16 test tubes.
We got these tubes for propagation purposes to root new plants. Tubes are 110 mm (4.25") tall and 25mm wide (1 inch).
The holder should be a pretty snug fit with a bit of tolerance so that it is easy to get tubes in and out.
I printed this in Polymaker Matte PLA. Layer height was 0.25mm and I did a 5% infill. I'd recommend 10-15% so it holds up long term - however at 5% it is plenty strong.
