Spider_Chuck_REVA_200.STL_10mm
Spider_Chuck_REVA_200.STL_12,5.STL
Spider_Chuck_REVA_200_5.STL

Update_20221218
add 5 mm tickness version (standard version) with round magnetic 8mm x 1 mm

Update_20221205
I made another version REV_A, where you can adjust the measure by small spacers tightened on spider chuck, in this way you can avoid to print all the spider chucks.
Pay attention because you have to print the parts and to drown a M3 nuts on the spacers and on spider chuck.
In any case the old version remains available.
