50 ml (and 15 ml) conical tube rack

thingiverse

This is a rack for 50 ml conical centrifuge tubes, with spaces in between for 15 ml conicals too). This is a member of my printable labware range, which aim to: * Be functional * Use minimal plastic, and so are quick/cheap to make * Require little to no supports * Take up as little bench space as possible * Can be easily tweaked and combined to make whatever related custom labware is desired Note that the new 'v3' version (with four supports instead of three inside each 50 ml holder) tends to print a little better, due to greater contact with the bed. This was made by duplicating the single [50 ml conical tube holder model](https://www.thingiverse.com/thing:3324289), then incorporating the 'hole' and base for the 15 ml tubes from [this model](https://www.thingiverse.com/thing:3324299).
