Sandpaper cutting templates for Curved Surface Sander and Bow Sanders

Just quick templates to cut sandpaper for sanding tools I found very useful. 

I just realized I should explain, the largest of them needs 265mm long sandpaper, which is larger than most print plates. I printed it at 250mm long, and it has a raised section 15mm long on the end opposite of the lanyard hole. So you would trace the jig on sandpaper including the end, then move the jig up until the start of the box is at the previous end, and make the line at the end, forming a 265mm long line easily with no measuring, just add the length of the box to the end.

The smallest of the jigs is for an adjustable mini sander, which has around 6mm adjustable length from shortest to longest. Same thing but opposite, full size is the large section, marking at the start of the box is the length for the most collapsed range of the sander. I personally like having adjustment, being able to have them floppy enough they are unusable unless you push hard, to provide a more gentle radius, to very tight and almost solid for sharper corners.

The three sanding tools these jigs are for are:

Surface Sander (both fullsize and mini, V1 or V2): Version 2 (without screws): https://www.printables.com/model/937895-curved-surface-sander-20-without-screws

I did modify both prints, extracting the clamping pads to print them in a better orientation, and using these 2 and 3 arm wingnuts.
