This is a bread slicer that can be collapsed into 4 pieces to minimize the required storage space. The slicer supports loafs baked in a 5" x 9" bread pan and knives that are up to 2mm thick. The source code for this design is provided 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.
- Stand a guide upright
- Inserts the base onto the guide pegs
- Stand the second guide upright
- Insert the other side of the base on to the second guide pegs
- Insert the stopper into the last knife slits of each guide
- Insert a loaf of bread onto the base
- Slide the loaf of bread until it reaches the stopper
- Hold the loaf of bread against the stopper
- Insert a bread knife into the slits in the guide opposite the stopper
- Saw the bread until the knife reaches the base and the slice falls over
- Remove the knife
- Repeat steps 4-6 until the entire loaf is sliced
WARNING: Be careful not to cut yourself when cutting the last few slices of a loaf.
- (v1.1) The guide pegs have been tweaked to allow the pieces to lock together for easier storage. The other parts are backwards compatible, so you just need to print 2 new guides to upgrade.
The large flat surfaces that make contact with the print bed may be difficult to remove depending on the material. When using PLA, consider using a glue stick or a raft to avoid print bed damage during removal.
A tolerance of 0.15mm is used for the interlocking pieces. This should create a tight fit, but may need to be increased to 0.2-0.3mm on printers with lower dimensional accuracy.
