Magnetic PCB Holder

Simple magnetic PCB clamp-holderSturdy as hell, reasonably low with optional raiser when U work with higher elements. Ideal to work with microscopeParameters:Used basic Bambu Lab blue PLA with .2 mm strength profile for printing25 mm diameter minimum 17mm heightmaximum with optional raisers not tested, keep in mind that quality of magnet strongly impacts thatoptimally for <2mm PCBs, for higher U might need to adjust holder modelsRequired parts:20x7 mm neodymium magnet - I used N45 class 12kg of max load , it holds as hell to my 3mm steel plate , think twice weaker would also do2 x 4mm nut1 x 30 mm flat head M4 screw , add 5 mm of height for each riser usedoptionally rubber/spongy furniture foot piece to add some springiness so U don&#39;t need to unclamp the clamp manuallyoptionally some isolating tape to reduce PCB slipping from clampU can observe both optional parts applied on last picture. Assembly is simple, just put nuts where U can see nut spot (bottom holder and screw head), and
