Very easy to load Sanding Block

Here's my remix of https://www.thingiverse.com/thing:4639552

I made this because I found the original to be extremely difficult to load sandpaper onto.

The sandpaper should be cut into a strip 15mm x 160mm long, and inserted into the sanding block starting at the 'heel' of the block as shown in some of the photos.

I've included a new option for the screw, which has a screw head extended by 6mm and might be a bit easier to loosen/tighten.

Note:
If you've already printed a screw for the original version, you'll only need to print the Main body and Top piece, since the screws are interchangeable.

I printed the top and bottom pieces with 35% infill, and 70% infill for the screw.

Changed the profile of the top piece, so that it can pivot into place, instead of having to slide it into position.
