Covering Film Trimmer

thingiverse

Used in the construction of R/C model aircraft to trim covering with varying amounts of excess to create overlapping seams. Three versions are presented here that provide for different overlap widths. Works well even with "bulk purchased" single edge razor blades typically used for paint trimming purchased at "big box" hardware stores. Narrow channels on the front of the tool guide the film securely to the blade and the wider channels all the way back trough the tool allow the film to separate cleanly. I can't say that the #2 tool provides for 2mm of overlap, but the 4 and the 6 each add 2mm and 4mm respectively to the #2 version.
