Publishing a project

So I tried and tried to upload a project for this Hour power challenge. If I don’t select a material from their list it won’t let me progress. But I only used stuff lying around my shop. Then I just add something from the list and then I have errors when I try to submit.

So my question is. How many people actually design something for these contests then just give up on submitting? Just curious. Was so frustrated even knowing my project wasn’t a new x-carve worthy but could have scored a gift certificate or something. Decided it all was worth it.

the trick would be to list a material with similar properties… doesn’t have to be exact, it just needs to know what to expect for hardness/variation so it can set the proper values for feed speed, plunge rate etc.
