Reusing pipet tip boxes by refilling with pipette tips purchased in bulk, followed by autoclaving has been going on in biology labs for a long time. The drawback is the time it takes!
Cheers and credit to easylabsolutions on youtube for demonstrating this 3D printed device which makes the task four times faster! The design file is available on Thingyverse in the DIY Bio Group.
Importantly, if you know CAD please share your designs adjusted for various pipette tip sizes or other 3D printing platforms.
Thank you for being Labconscious!
