Tiêu đề Vỏ ống NMR Tóm tắt Hộp vận chuyển cho ống NMR đư

In order to run NMR samples at work, we need to prep everything in the lab then run the tubes to the other side of the building where the NMR instrument is located. To make our Health and Safety guy happy, I made up a transport case for my tubes. The base makes a nice tube stand, and the cover keeps them protected when going back and forth from the lab. I printed mine in PETG. I used a print temp of 240 with a bed temp of 85. Recommend a fast travel speed and use filament retraction (I used 2mm) to cut down on stringing. Print speed shouldn't be any higher than 50mm/s for good layer bonding and low speed cooling fan. I used rectilinear infill of 20%. Modeled using FreeCAD 0.21 with the help of the ThreadProfile workbench.
