STL RE-DO ASAP

Job ID: 32362743

Budget: $10 – $40 USD

I have an STL file i need someone to make revisions to or possibly re design... im not sure how the process works.
canadite must be willing to do multiple corrections before releasing payment.
I have wasted 12 days with another freelancer who has delivered unsatisfactory work and is unwilling to fix.
id like the file he did modified in four ways.
1.) needs to be shorter (3 inches in length )
2.) needs to be rendered for the flashforge creator pro 2 for flash forge slicer. I dont have time or knowledge to change anything around with my slicer and make it work so please be willing to format the file in a way that will require no further edits.
3.) the diameter of the hole in the straw needs to be just a tad bit wider for string to pull through
4.) canadite must be able to modify immediately and deliver within 2 hours after completion
this is TIME SENSITIVE. 1 DAY BIDS ONLY PLEASE

looking to pay nothing more or less than $40 USD for the edits
