Loaf Slicing Guide

Did you 3D print this model?

3D model description

Store-bought bread usually comes sliced already or the store can slice it for you. We have been making our own bread almost every other day for quite a while now and we've been wanting to slice our bread more evenly so it fits the toaster better and looks nicer as well. This thing helps us do exactly that.


This fully-printable slicing guide can be adjusted to hold different loaf sizes (between 110mm~160mm width). Each slice is about 14mm thick or you can double that for Texas Toast.



3D printing settings

Dimensions of parts:


(X,Y,Z) (mm)


Base: =109, 180, 12

Guide: =128, 165, 30

Nut: 11.2, 11.2, 5.5

Bolt: 7.4, 7.4, 100




Base: L+R one each / any layer height

Guide: L+R one each / any layer height

Nuts: 4 on one side, 8 for both sides / at least 0.15mm layer height

Bolts: one for each side, 2 for both/ at least 0.15mm layer height


Using only one set of fasteners ( 4 nuts+ 1 bolt ) on only one side of the base is usually good enough to hold the parts, but fastening both sides will of course make it extra secure.


Print the nuts and bolts separately to minimize crossing of the perimeters. If you are getting a lot of oozing from crossing perimeters, try slicing the nuts with Slic3r v.0.910b. From my experiments only this version will not move the oozing nozzles across the perimeters when printing the nuts. Newer versions will make the crossing and leave unwanted ooze and messy surfaces for the nut threads.


There are click snaps at the end of the base slots, be careful not to break the flaps when you push the slicing guides into the base slots. If you are having a hard time making the click snap, sanding or filing the contact area just a little bit will help a lot.


All the fitting parts have tolerance value on them, so they should fit nicely unless your printer is really off. If that is the case, I usually recommend running the part fitting calibration ( thing:342198 ). It is a good idea to print the nuts and bolts first to ensure a good fitting before printing the bigger parts.




Adjust the slicing guides and fasten the nuts to hold the bread steady. Hold down the bread when slicing for extra support.
