This is a generic Stamp Holder that I have custom fitting our stamps here in Belgium. Holds the stamp Tightly but your stamp may differ. Outside is about 4mm thick.

X32mm x Y49mm x Z61mm

Inside is 25.4mm by 42mm unless you scale it of course.

Personally, I print these in PETG CF, works really well and is study and has the carbon fiber look to it.

.2 to .25 layer height is good for texture
