Vacuum capacitor bracket

Insîred from https://www.thingiverse.com/thing:2252121
The bracket was designed to clamp a KP1-4 5-100pF 25kV variable vacuum capacitor together with the 28mm diameter ends of the copper tube from the magnetic loop antenna.
The contacts of the capacitor are 52mm diameter. The cut-outs in the clamps are 30 and 54mm diameter because there is a 1mm thick strap of copper plate running around bouth the capacitor contact and the copper tube, to connect them
