Low-profile wheels/rollers for Midea SF 5.45NW10C dishwashers

Updates

• 07/2025: Made the rollers and clips slightly deeper to avoid occasional slips from the rail (clip v1.9/roller v1.5).

Description

Modified wheels/rollers for Midea SF 5.45NW10C dishwashers to increase the clearance between the lower and the upper basket, allowing for larger diameter plates to be cleaned.

These modified rollers increase the clearance between the two baskets by 6-7 mm. This allows plates of up to 270 mm diameter to be cleaned. The wheels and clips are essentially as low profile as they can be without compromising their structural integrity.

This mod is likely to work on similar Midea machines like the Midea SF 5.60NW14C, but for obvious reasons, I have not tested it. Feedback welcome.

Installation

Remove the original clips. Then install the low profile rollers onto the printed clips and install the assembly on the basket. I recommend to add a drop of rapeseed or sunflower oil on each printed clip before installing the rollers to reduce the initial friction. The oil will wash away in a couple of cycles, but the clips and rollers will equally “break in” and friction will stay medium to low-ish.

Print settings

• Layer height 0.2 mm
• Line width 0.42 mm
• 7 wall lines
• 5 top & bottom layers
• Supports not required
• Scarf seams can be helpful to avoid “bumps” on the rollers

The material should be one with a heat deflection temp of ≥65°C. PETG works for low temp cycles and has low friction. ABS/ASA or PC would be better and should also work for high temp cycles.

Approximate print time @ 60 mm/s: Clips 0:08 h per piece / Rollers 0:09h per piece
