Hairbrush Holders
These hairbrush holders were a small weekend project done with the intent of tidying up the bathroom counter by providing space to store these commonly used items within arms reach. These hairbrush holders will be designed to accomodate the cylindrical and oval shapes of the brush and will be secured to the side of the sink. This will be the first type of print I adhere to a surface using adhesives sufficient enough to support itself and contents for a significant period of time.

Cylindrical Hairbrush
This print is intended to be mounted and hold the cylindrical hairbrush providing enough space to expose the brush handle. The brush head has a diameter of around 60 mm and a height of around 115 mm and with these dimensions an appropriate space was created to fit the brush. A hole was also left towards the bottom to allow hair and dust to fall through. Lastly a square (26.50 mm x 26.50 mm x 1.50 mm) for the adhesion sticker was inset into the print to keep the print flush with the surface.
This print was completed in just under 9 hours and utilizes a low quality extruder width of around 0.28 mm since there were no real intricate details to capture in this print. Towards the end of this print the space gray color filament was close to running out and thus the print was paused and filament swapped with the available light gray. This is quite visible in the print but does not detract from the integrity of the final print.
The hairbrush fits well into the holder and does not fall through the hole towards the bottom. The holder used a diameter of 65 mm for the measured head diameter of 60 mm, thus fits pretty loosely. This is fine as it still achieves the goal of providing a slot to store the hairbrush besides the sink countertop.
The stickers however had a measured height of around 1.80 mm but an inset of a depth of 1.50 mm was used here to expose enough of the sticker to the intended surface. This proved to work well as the print is secured to be flush with the medicine cabinet. I believe that this is because there is small 0.02 mm of space between the print an cabinet.
1.80 mm [sticker height] - (1.50 mm [sticker inset] + 0.28 mm [extruder width]) = 0.02 mm [space]
Oval Hairbrush
The "oval" hairbrush has bristles that protrude from the oval brush head in a cresent shape. The length from the head of the brush and the end of the bristle was measured to be approximately 45 mm. The width of the brush head is approximately 65 mm and along with the height dimensions, these values were used with the arc tool in Fusion 360 was used to sketch out the cresent slot for the brush head. The first version of this design did not include the 15 mm of space to account for the sink counter overhang and to account for this 20 mm of extra space was added to that side of the print.
The print here uses the same settings as the previous hairbrush holder (0.28 mm extruder width and 10% infill). The print time was estimated to take just over 14 hours and was completed in just under 13 and a half hours. Adding this extra material between the surfaces added around an extra 3 hours of print time as V1 had an estimated completion time of 11 hours and 19 minutes.
The print finished correctly with a couple of small defects between some of the layers. Overall, the space made for the brush and adhesive stickers fit very well.
Instead of next to the sink counter, the brush holder was placed inside the sink cabinet as it would be directly outside of view. This is a design consideration I did not think of until I sought outside feedback and will take this into consideration for my future projects.
With these hairbrush holders in place, the sink counter is a bit tidier. For a home improvement projects like this, I will make sure to involve the considerations of the home owner during the design process to best fit their constraints.
