Improved Bosch dishwasher wheel

Update 2026-02-16

The ABS has completely disintegrated.  I printed another set in PETG as a bandaid, but don't expect those to last long.

Once those fail, I'll try MJF (nylon).  And after that, maybe try a mold + silicone?  ASA also recommended as being a bit more chemical resistant.  Resin can work, but smells for a while.  The real problem is that FDM materials and methods can't last long in this enviro - evidently dishwashers are ugly to plastic (hot/wet/chemicals).

Will update again once I sort out what material works best for the long term.

The ABS order from JLC works perfectly, wheels did not melt, and the problem is completely solved.   Family very happy, job done!

Overview

We've lived with this dishwasher and its atrocious wheel design for too long.  (Dishwasher model: SHE65T55UC)

There are ‘updated’ wheels from Bosch that don't solve the problem - which is that the track width of the lower dish holder tray thing is too narrow.  And these updates are super expensive.

So, all I did was reproduce the basic dimensions (10mm ID is the only crucial one, and the angle is ‘pretty close’) and then widen the track.  With the old design, there was ~7mm clearance (total) between the wheels and the walls.  Now there's ~1-2mm clearance.

We tested with a full load of dishes, and it was rock solid in both closed and open positions - my wife was extremely pleased.

Now, I tested with PLA - an ABS order has been placed with JLC - so let me know if things don't pan out for you.

Install notes

Getting the clips separated from the wheels is dicey without the right tools.  However, effectively what you need to do is press them out, they are designed well in that regard.  :D

I used a drill press chuck tightened down all the way, but any kind of suitably sized punch will work.  Annnd since I was in there, I've included a printable 14mm removal punch to help.  The pictures hopefully illustrate the theory of how you want to use the punch.

Again, the key point is that you need to get all the clip-teeth disengaging simultaneously - using pliers will wreck it.

Printing notes

Dishwashers get quite hot - hotter than PLA or even PETG can reliably handle - so you'll need to use something like ABS.  As I'm not familiar with high temp filaments, I elected to go with a JLC order.  I will update this description when I get the final product.

No supports needed (ensure printed with the wide side (largest diameter) facedown on the print plate.
