Hi Terry,  I use to use a few different nylon standoffs that I was 
sourcing from mcmaster-carr and paying pretty high prices (especially 
since they don't offer any quantity price breaks). Now that I have a 3D 
printer, I've started banging out standoffs using PETG and satisfied 
with the results.

The ones I've been making though haven't been threaded and 4-40 thread 
is likely way too small to print. If you went down that road though, you 
could experiment with the inner hole size until you have something your 
screws could self-tap into - the PETG is pretty flexible.

Let me know if you go down that route and I can share some lessons 
learned from getting the printer to bang out hundreds of these small
