Sensitive tape holder

It is designed to hold a spool of sensitive tape and has a handy toothed area for ripping the tape. It seems that a 0.2mm layer hight works best to generate sharp edges. 0.25 and higer dulls them to much to be of any help anymore.

Note: First i made them out of ABS to make the latches in the middle more flexible, but i found out that the teeth out of ABS are rather quickly worn out by tape with a high fiber content. 

PLA seems the better choice therefore. Wouldn't have expected that

I derived this roller by printing this one first:

Unfortunatelly, it didnt survive to long because the middle section disintegrated while using. This might not be the designs fault, cause i printed it very fast out of ABS. But to tacle this in the first place, i designed one with thicker latches and made it a little biger in general
