Multiboard 25x5 Magnetic SNAPs 3 Sizes DS-Part A

I needed a way to attach Multiboard to the side of my equipment rack.  I built these Multiboard Double Sided Part A Snaps with 25x5mm Magnet holes.  I wanted the magnets to hold a decent amount of weight so the board doesn't move since it is not supported on one side.  

I liked the way they came out I decided to use them on some metal surfaces in the garage.  I am doing larger multiboard so I also created dual and quad snaps.   The standard DS-Part B covers will work on these snaps.  Since its going in the garage I use PETG for this, not sure PLA will hold up.

I used these magnets.  https://www.amazon.com/dp/B0CZLCGVGG?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

I am still working on making a Parametric version so you can use any size magnet.

Note:  The tolerances are tight, you wont be able to push the magnet in by hand,  I used a rubber mallet on a solid surface to give it a tap.
