Dụng cụ gắn nam châm tròn 10mm

Need something to hold magnets while glueing a large project together and need polarity to be correct. Found this one and resized it to 10mm.

Will hold a 10x2mm round magnet. Shorten the rod for thicker magnets. 

Used manual tree supports for the inside of the case. 

I printed with .6 nozzle at .42.

Made a red version for one polarity and a black for the other.

Added a piece of heat shrink to the end so that it was a little more snug fit. 

Original designer also used Ferrules Rubber End Caps on the end to aid in glueing. I ordered some from Amazon but they have not arrived yet to try.
