About this 3D model

I designed this lab rack holder to function as a replacement on opentrons machines to hold 6 50mL "Falcon" style test tubes for a covid spit testing process. This rack is an all in one design and prints with about 73grams of petg and takes me about 1 hour and 25 minutes per or 5 hours and 40 minutes for a batch of 4. Please feel free to print and use this design at will but selling these prints is not permitted. If a lab is in need of them and you wish to print them for them they can supply the filament or reimburse for material cost ONLY this design is not for profit. Please view print settings for an important note regarding z height of the top surface of the rack for complete compatibility with the stock racks.
