This is my design of a functional, robust and reliable door or drawer handle. I created it especially for the FFF process to be printed using PLA, PETG or ASA. The handle is mounted from the front, using two countersink screws. This keeps pressure on the printed layers and prevents the handle from breaking on large pulling forces along the layer lines.

How to Print the Handle

Print the handle on the flat side from the front. Larger handles have a tendency to wrap, make sure you add a brim or mouse ears at the ends of the handle.

I created an example project LR2225-W160-D30-H22-M5 Print.3mf for Prusa Slicer, where all required settings are made. If you need to create your own setup, check out the following table:

Nozzle Size:

0.4mm, 0.6mm or 0.8mm

Layer Height:

0.2mm for 0.4mm nozzle
0.3mm for 0.6mm nozzle
0.4mm for 0.8mm nozzle

Filament Materials:

PLA, PETG or ASA

Perimeters:

3 perimeters (important!)

Prusa Slicer Profile:

“0.2mm Quality”

Dimensions

The part number and file name have the following format:

LR2225-W<hand width>-D<hand depth>-H<handle width>-M<screw>.3mf

Hand Width and Depth

The dimension W and D define the width and depth of the spacing for the hand. The number after the letter in the filename is the dimension in mm.

Handle Width

The dimension H defines the width of the handle, which also defines the thickness of the handle (H * 0.75). The number after the letter in the filename is the width in mm.

Screw Hole Diameter

The last dimension M defines the size of the screw hole. There are two variants, M4 for M4 wood screws with countersunk heads, and M5 for 4.5 or 5mm screws.

Screw Hole Distance

The distance between the two screw hole centres (S) are not round values, because they are centred in the best spot between the outer in inner side of the handle.

If you need to know the exact distance for the various handles, you find the exact numbers in the table below:

About the Design

Handles on doors and drawers are usually mounted from behind, to hide the screw from plain sight. 3D printed parts (FFF) tend to break along the layer lines, therefore fastening the handle just at the lower half is no option.

Because of this risk, I decided to fasten the handle from the front side. The screw will press the part from the front side to the door or drawer and therefore presses the layers together. If the user pulls on the handle, it will convert most of this pulling force, pressing it to the screw head which will move the door or drawer.

Precautions when Mounting the Part

Make sure you fasten the screws carefully by hand. Otherwise, the material will crack. Also, be aware, that PLA will permanently deform under pressure. Only apply a light force on these parts or use PETG/ASA if you have to move heavy parts (heavy doors/drawers).
