Description:

I liked the magnetic rack design by RyanMulqueen for 0.2mL PCR strip which can be used in high or low position, so I reproduced the design with minor changes to fit my needs.

Main modifications:

  • Small reduction of the hole size for the PCR strip to reduce wobble I had with our eppendorf 0.2mL strips
  • Modified the magnet hole size to fit 6x3mm N35 magnets I had
  • Made a simple plug to force fit into magnet holes

You can stack 2x (6x3mm) magnets for increased strength (One N35 magnet worked on the original design but was weaker than a commercial rack in our lab).

Print Settings

Printer: Ender 3 Pro

Filament: Eryone PETG transparent blue

layer height = 0.2mm

Supports: yes

Assembly:

To insert the magnet plugs, I laid the rack flat on its front on a table and gently forced the plugs into the holes where I inserted the 2 magnets with the handle end of a screw driver (you could also use pliers).
