Customizable low filament bottle dryer

This model is the perfect solution for anyone who wants to dry their bottles easily, effectively and without any hassle. It is suitable for bottles with a neck diameter of up to 45 mm and, thanks to its design, ensures optimal ventilation whilst catching every single drop of water, keeping your kitchen clean. Thanks to a flexible spring mechanism, the bottle sits firmly in place and won’t tip over, yet it’s still easy to remove. I’ve already uploaded six different spring versions so you have a choice and can find one with the correct dimensions. However, if that’s not enough, I’ve also uploaded a Fusion 360 file where you can easily set the correct dimensions parametrically to suit your needs. It’s also very straightforward to design your own springs. During the design process, special care was taken to ensure that the dryer is easy to wash and dry. The model is also very filament-efficient, weighing in at only around 15g (depending on the version). No glue is required for installation, and thanks to the press-fit design, it’s very straightforward.

Selection Guide

All versions use the same base plate - the only thing that changes are the springs. I have labelled each spring with two numbers. The first number describes the height of the spring – that is, the distance from the surface on which the bottles stand to the centre of the spring head, measured at right angles to the base. I would choose this so that the head sits just above a protrusion, ensuring the springs hold the bottle securely and it doesn’t slip out. Sometimes you need to choose a slightly shorter height because the springs end up a bit higher when they’re bent outwards. The head itself has a diameter of 4 mm. The second number describes the distance from the axis to the front of the spring head, measured at right angles to the vertical axis of the dryer. For example, I use the 18 mm version for a bottle with a diameter of 42 mm at the point where the spring will grip, and the 16 mm version for a bottle with a diameter of 38 mm.

Customisation Guide

There are two ways to customise this bottle dryer. You can draw the springs yourself; the recesses measure 7 mm long, 3 mm wide and 10 mm deep. However, I have also uploaded the Fusion file, which contains all the versions uploaded here in parametric form. You can simply create a new configuration parametrically (in the configuration tab) and just enter the parameters described in the previous paragraph as required.

• PLA

• 15% infill

• no supports

Disclaimer: As I design for the very tight tolerances of my MK4S, you may need to sand down certain parts slightly or adjust them in the slicer to ensure the springs fit properly.
