If you are putting pvc side bands on the edges of wooden plates of any kind, then you have probably faced to the excess pvc out of the edges. Here this gadget is exactly for trimming off these unwanted part of edge bands. Design of this trimmer enables us to use these cheap blades readily available in markets.
It needs extra three M4 bolts (20mm) and nuts. Part2 (blade cover) of this thing has housings for these nuts and it is used to fix the blade in its place. When blade gets dull in a period of time, just take off the bolts, open the cover and rotate it to use the other side of the same blade.
I use PETG filament and prefer manual supports to print this. Bolt holes do not need support structures. I have arranged the proper standing positions of the parts in the stl files. Use as they come into the slicer plate for minimal supports.
Enjoy it.. :))
