  The For­ward- scat­ter­ing Fixed-Tar­get cham­ber (FFT) hosts the co­her­ent dif­frac­tion imag­ing ex­per­i­ments, which are the base­line ex­per­i­men­tal stud­ies to be per­formed at the Spec­trosopy and Co­her­ent Scat­ter­ing (SCS) in­stru­ment of the Eu­ro­pean XFEL. The sam­ple en­vi­ron­ment al­lows for chang­ing sam­ples with­out break­ing the vac­uum. This is re­al­ized by a fast sam­ple changer sys­tem con­nected to a load lock. With dif­fer­ent and cus­tomized sam­ple hold­ers it is pos­si­ble to achieve user spe­cific re­quire­ments. This poster de­scribes the process of con­vert­ing a Com­puter Aided De­sign (CAD) file into a Com­puter Aided Man­u­fac­tur­ing (CAM) file, which in turn is con­verted into Nu­mer­i­cal Con­trol (NC) code. The sam­ple holder is man­u­fac­tured on an adapted CNC ma­chine, with a vac­uum table and spe­cially se­lected tools. In ad­di­tion, all im­por­tant me­chan­i­cal and vac­uum bound­ary con­di­tions are ex­plained. Due to the adapted processes it is pos­si­ble to react im­me­di­ately to changes dur­ing an ex­per­i­men­tal cam­paign.
