Castors for laundry drying rack

Most drying racks have a tubular frame with bent tubes. The castors are attached as far out as possible at the bends, i.e. at the “corners” of the legs. This provides better stability. On the drying rack itself, only the feet clipped onto the tube need to be removed. Nothing else is changed, so it can be completely dismantled.

The upper parts are the same for all corners.
There is a left-hand and a right-hand version of the lower parts and the brackets for the castors.
The angle between the floor and one of the legs is 51°.
There is also a 47° version for the brackets.
If the legs of the dryer are at a steeper or flatter angle, you can compensate with wedges. The file “wedge.stl” has an angle of 2° and should be printed with a very small layer height. Always use in pairs.

The tube diameter is 16.4 mm.
The bracket is suitable for different pipe bending radii.

Disadvantage: Folding is no longer possible.

Screws per castor:
5 PT screws 3 x 14 mm countersunk head
4 M4 x 14 mm screws, washers, nuts
6 M4 x 30 mm screws, washers, nuts

The square mounting plate of the swivel castors must not exceed 42 x 42 mm. The hole spacing may be 26 to 30 mm.

The brackets must be printed on the side. This gives more stability.
Print with ASA (must be UV-resistant). PET-G if necessary.
20% infill, 0.3 mm layer thickness

First screw the mounting bracket to the matching lower part (5 x PT screws).
Then screw the castor to the mounting bracket. Screw heads at the bottom, hexagon nuts at the top.
Finally, place the upper part and the lower part including the roller on the tube from both sides and screw them together. Do not overtighten, in the CAD there is a 3 mm gap between the upper part and the lower part.
