Modular Eppendorf Tube Rack V2.0

This is a modular test tube rack system that is an improvement over my old system which you can find here https://www.thingiverse.com/thing:488762 and here https://www.thingiverse.com/thing:1132367

This takes more filament and each module is taller than the old version, but the modules snap together securely and will never slide out. Of course they are still multi-channel spaced, as always!

Let me know if anything doesn't fit well! I can adjust the dimensions if needed.

IN PROGRESS: pcr tube magnets have not been designed with this version. Please use the old version!

Included modules are:
4x4 PCR tubes (the spacing is a bit off for these. Sorry)
2x2 1.6mL eppendorf centrifuge tubes
2x2 square 2 mL cuvettes
2x2 11mm sample vials (special request!)
2x2 2mL eppendorf tubes (great for primer tubes or miniprep columns!)
2x 1.6mL eppendorf magnet rack (use http://www.kjmagnetics.com/proddetail.asp?prod=B842-N52)
2x 15mL conical tubes
1x 50mL conical tube
