Case Holder

A tool - with four independent adjustable pins - for watchmakers. This relative simple tool can be used for example, to clamp a wristwatch tight, before opening the casing cover. The case holder itself can be clamped between the jaws of a bench vise. Notes: + The real manufacturing lenght of the compression spring is 36 mm (measured from the ORIGINAL) - The threads are modeled without clearance. + All components are relatively easy to selfproduce. + For PTC-Users: The compression spring is flexibly assembled. By changing the length in the assembly file under "Edit Definition/Flexibility/Varying Elements/Parameter" the opening width of the tool changes automatically after regeneration.
