Magnetic probe holder for aquriums

I used 2 sealed magnets from my Eshopps frag rack that measure 30mm x 12mm

Best to print in ABS or PET

I used modo to export the STL, in mattercontrol I have to edit go to scale and change the conversion from cm to mm, then it is the right size. (not sure why)
Edit: I figured it out and uploaded a fixed file, so it's in mm not cm.

with the slanted part up on the part that holds the probes the far left is for the temp probe as it is slitly bigger.
