Magnet/Pin Capillary Holder for ANL Advanced Photon Source SBC X-Ray Crystallography Beam-line Prep (Parametric) by jwerblin

This is a design intended for the Structural Biology Center (SBC) at the Advanced Photon Source (APS) at Argonne National Lab (ANL) as a mount for x-ray crystallography.
It is parametrized, so if you find the tolerances or exact size doesn't fit your specific magnet or pin, just change the parameters a bit in the OpenSCAD file. OpenSCAD is a free, pretty lightweight software, so you can change the file pretty easily if needed.
Use your printing software to find out the last layer where the top is open and pause the print on that layer. Once paused, push the magnet into place and then continue print (as seen in image 5)
This can be printed with or without the groove.
This can also be printed with an open bottom so you can push in the magnet from the bottom. If you want this, turn "Embedded" to false. If you do this, you may still want to stop the print and place the magnet in place as a way to hold up the plastic, as most printers can't print a flat cover over an empty cylinder hole. You may also want to make the MagnetShellRadiusTol a bit bigger to be able to slide in and out the magnet. With default settings it is pretty snug.
PRO-TIPS:
-Use your software to manually move the print head away from the print when it is paused so you do not melt the print.
-Keep the magnet on the print-bed so it heats up and can be printed on more easily
-My printer struggled to print onto the magnet, so be prepared to stick a poker of some sort (I used metal forceps) to squish down the hot plastic over the magnet for the first couple layers over it. This will likely mess up your groove, so you may want to set "Groove" to "false".
