About this 3D model

THIS DESIGN IS NOT TO BE USED FOR PROFIT This is a 5mm thick quick to print skeletal body tube holder with top skin for 6 tubes in an Opentrons holder. I have added versions with multiple hole size options. You may need to choose a smaller or larger hole size to suit your printers tolerances. 29.6 is likely to be too tight and 30.3 is likely to be too loose. In my case 29.85 was the hole size I settled on for best fit. This is designed to print quickly with minimal material usage.
