Had to adapt the model to fit my printer, so why not post here as well to help who doesn't have the knowledge to do so.

Original Description:

Remix of bread cutting guide at https://www.thingiverse.com/thing:2794539 with 2mm notches/grooves added to prevent knife teeth from scraping plastic bits that would contaminate the bread. 

This is a bread slicer that can be disassembled for space saving storage. This design is for loaves baked in a 5" x 9" bread pan and knives that are up to 2mm thick. The source code for this design is provided in the original design linked above so that it can be modified to support other bread and knife sizes.

You will need to print (1) base, (1) slide, and (2) guides.

To assemble:

1. Stand a guide upright
2. Inserts the base onto the guide pegs
3. Stand the second guide upright
4. Insert the other side of the base onto the second guide pegs
5. Insert the stopper into the last knife slits of each guide

Printed in PLA with 20% infill. No supports needed.
