Spraycan holder, snap-in and fully parametric

Spraycan holder for spray cans or other round cans with a diameter of 53, 58 & 66mm (all the sizes I had in my metal can collection). The can is held in place by the snap-in clamp and the weight of the can is supported by the lower part where the bottom ring of the can sits in a notch. Easy to take out and put back.

Model is designed in 2 pieces to maximize strength by printing in the correct orientation. No supports or elephants foot compensation (due to chamfering) is needed . Uses <5m of filament to print, even when combining the biggest models of part 1 & 2 .

The holder is attached with 1 or 2 screw to the wall. 

The attached model stl files are with a default can size of 53, 58 & 66mm diameter, 3.2mm wall thickness, a 4.3mm screw hole, 8mm screw head and several holder lengths 100-200mm. A step file for both parts is also added for easy modification in other software.

I printed them in PLA and PETG and both work equally well. Both are printed very strong (because of the print orientation) and can hold the large cans (tested with large brake cleaner can of almost 1 kg).

The model is adjustable for uses with other can geometries by adjusting the parameters in the Onshape model (link is below the model files, also see the attached image):

• Can diameter, 66mm default
• Holder length, 150mm default
• Holder height of top part, 10mm default
• Lower part width, 8mm default
• Holder thickness, 3.2mm default (top & lower part)
• Screwhead diameter, 8mm default (resulting hole size 4.3mm)
• Bottom notch size, 2mm default
• Top-lower part tolerance to make the holder and magnet snap fit depending on you printer calibration

In Onshape ,just double click on the parameter to update the values . To export the modified model to a stl in Onshape, just right click on the part 1 or 2 and and select export (default format is STL)

For best holding performance, the selected can diameter should be as close as possible.

Optimal length is that the top of the can is held by the clamp.

This design was inspired by this model  but that could not be modified and can only be printed so that the clamp relies on interlayer adhesion for strength so this design was born :-)

Please post a make if you printed the model.

A can holder that uses a magnet to hold the spraycan, can be found here.
