Kẹp giữ cọ + mép gạt sơn cho thùng sơn (parametric)

Update: Added parametric Fusion360 file, see below for parameters.

For house and interior painting, I (and most pro painters) paint from a steel paint bucket. (You only take the amount you need from a bigger tin. And a big 2.5l / half gallon tin gets a bit heavy after a while 😉).
For the steel buckets there are cheap plastic liners, so you can easily change and store the paint. I was missing a brush holder, as I usually use at least two brushes (normal + precision). Sometimes you need two hands free, and just dropping the brushes in the paint makes things messy. These brush holders clip onto the common size bucket liners (at least common where I live… In the pictures there is a cross section of this liner).

I made two versions: 
-A has just the two brush holders.
-B also has an edge to wipe the excess paint from the brush. Works a bit cleaner than wiping on the edge of the bucket: less chance of dripping paint on the floor.
I'm lefthanded, just mirror the part if the wipe edge works better for you on the other side of the brushes.

Printing

Printed in PETG, 0.4mm nozzle and 0.6mm extrusion width.
Print upside down, with support for the curved edge and the inside lip (see screenshot).

Parametric model
The Fusion360 model makes both A and B version, just export and print the one you need.
The model can be adjusted through the parameters; the most important are listed below:

- ID_container and OD_container: inner and outer diameters of your paint can or paint bucket.
- clr: clearance between the container and the clip; to make it more loose or tight.
- d_clip1 and d_clip2: inner diameters of the brush clips.

(the lip is the part that clips over the bucket or paint can.)
- h_lip: height of lip.
- t_lip: thickness of lip, adjust so it holds on to your can or bucket.
- r_lip: radius of upper outside edge.
 

- x_clips: the distance between the two clips.
- x_wipe: the length of the wiping area.
- x_clip_wipe: distance between clip and wiping area.
- w_wipe: width of wiping area.
- t_wall: thickness of wall.

As always, feedback and suggestions for improvement are welcome.
