Get measurements and I'll try.
I currently use PLA which probably isn't so great at those temperatures. I do have some ABS that would probably do the job.
Couldn't get the measurements last night as the dishwasher was already prestacked with dirty implements and I didn't want to get curry sauce on my ruler. It's been on overnight, so I'll be able to get the sizes this evening come tidying up time.
Ye gads, it's shaping up to be a fascinating Friday evening.
I've measured up and I'd need 8 lots of a 40mm x 54mm mesh. The holes would need to be around 2mm square, big enough to let water through, but small enough to hold the cutlery.
We'd looked at a replacement a few weeks ago, found an original on Amazon and it was £25 - £30, which made me rather vexed. I wanted a cheaper alternative, but the cheaper non-original ones didn't have the deep grooves which allow it to fit over the racks. The product link's here.
I now see that the current prices are somewhat more appealing. :-$
If Ant or Throb are willing to make a mesh insert with postage for less than £9.20, then I'd much rather send the cash their way than Amazons (or a third party). :)
