I thought that it would be nice to have a common topic with a collection of 3d models made by the Rhino community. 
I will start with uploading several simple 3d models primarily made for 3d printing. All tested and working perfectly fine for months.
Vacuum cleaner attachment 90 degrees.3dm (1.2 MB)
The upper portion is split into two halves, in order to 3d print all 3 pieces based on the forces that they will endure. As a bonus, it does not need additional supports for 3d printing that way. A super glue is required to assemble the 3 pieces together.
Very usable to tight areas where the standard vacuum cleaner tip can’t reach. Due to the irregular less aerodynamic shape, it’s extra loud, but that’s a small sacrifice for the sake of cheaper 3d printing and overall strength required for such an attachment.
The attachment fits standard 35 mm vacuum hoses. It varies from 35,5 mm to 34,6 mm.
Vacuum cleaner attachment long 45 degrees.3dm (486.7 KB)
A single-piece, longer version, designed to reach super tight areas.
The attachment fits standard 35 mm vacuum hoses. It varies from 35,5 mm to 34,6 mm.
Ключе за чешмата.3dm (1020.8 KB)
Aerator removing tool that fits 24 mm aerators with 6 teeth and 18 mm inner diameter. I urgently needed a specific size for my kitchen aerator, so 3d printing it on my own was the best way I could get it in less than 30 minutes, including the CAD design. The 3d printing itself took a little bit less than 20 minutes.
Initially, I 3d printed the shorter version, but then I realized that longer handles would make the job much easier, this is why I extended them and share both version just in case.
Battery holders.3dm (1.9 MB)
3 different battery holders, designed for AA batteries. One of them has pockets for AAA batteries, too.
Phone stand basic.3dm (2.0 MB)
Phone stands 4 cat.3dm (1.9 MB)
5 different phone stands. All work perfectly well with various iPhone and Samsung models.
The first one (basic) is made of two separate pieces, so a super glue is needed. For convenience, I placed the upper piece vertically, which is needed during 3d printing. The inclined version shows how the final part must look like.
The rest 4 phone stands are shaped like a cat. Two of these are hollow, which allows an easier handling of the phone.
Mop holder 22,5 mm diameter.3dm (1.7 MB)
This is a general purpose holder, clip, grip, hook, hanger or bracket that can be utilized in a variety of applications. It’s primarily designed to hold 22 mm diameter handles used in telescopic cleaning mops and other household tools and objects that provide a larger ring on the handle. To ensure a greater compatibility with variety of objects, the grip diameter is set to 22,5 mm. There are two raised tips at the top to keep keep the mop in place and prevent an unwanted detachment. The center of the grip diameter is 51, 25 mm away from the wall, which should be enough to prevent touching the wall with the wet sponge.
In case that you install the holder on a wall via a basic wood screw, it’s recommended to use the included conical washer to spread out the pressure evenly and prevent cracking. You don’t need the washer when using a machine screw (up to M6).
Important: This holder is designed for use with screws whose head diameter is less than 11 mm, and length must be at least 35 mm when using wood screws to ensure that they will provide at least 10 mm long grip into the wall! Make sure to check your screws for compatibility.
Holds the cleaning mop where the wider blue plastic ring is located in the middle of the handle. Simply put it over the 3d printed holder and voila.
SDS Plus tool holder.3dm (2.7 MB)
A tool holder for SDS-Plus attachments. Of course, if you modify the hooks (size and shape), they could be used for various other tools, such like drill bits etc. The hooks are separate and don’t need to be glued, because I designed them to install by a small rotation and they just click in place firmly. However, you can still disassemble the tool holder when necessary.
The hooks must be 3d printed sideways to provide maximum strength.
I made two version, with one being cheaper and faster to 3d print due to its U-shaped body.
Basic hook.3dm (715.2 KB)
Just a basic hook that has a couple of 4 mm holes for wood screws. Must be 3d printed with the back flat wall pointing to the 3d printing bed.
