Precision Rifle Gear 3d printing bore guide question

[LRshooter6mm]

I’m going to print a bore guide for my Curtis 22lr conversion since no company makes one. My biggest concern is making sure the solvents don’t break down the plastic and get gunk in the barrel. What types of plastics would be best for making a bore guide?

Thanks in advance

Have you considered turning one out of Delrin in a lathe? I think this is what a lot are made from.

I’ve done some out of PETG.
No issues.

I don’t have access to a lathe unfortunately. My best bet is to print something

Does PETG have good chemical resistance?

I’ve used the bore guide for my CZ-457 for at least 2 years now with no issues.
The bore guide costs less than $2.00 to print so worst case I throw it out and make another one.

I have made bore guides out of pla pro. I haven't had issues with it. I am using c4 and tomorrow blend in mine.
The big thing is you are only going to be using mild corrosives. I think you'll be ok with either petg or PLA pro. Mine have down no signs of breaking down over a few years

We use all kinds of filaments in the print farm at the shop and have tested them in various situations. I would not recommend one that has carbon fiber in it - nylonX, NylonG, etc. they are hygroscopic to a degree and can absorb fluids so it makes cleaning them a pain after the fact. Also the finish can be rough compared to other filaments and Delrin so it could grab patches, etc.

Granted there are printers that can make the cf prints smoother, but we have found the absorption characteristics remain and it is especially bad at the layering points and angle changes regardless of the printer and filament brand used. We even found this with Markforged material. After conferring with them on it we determined together that the only way to fully prevent this was with a conformal coating which is way outside the scope of your project.

Did you miss the "no issues" part?

If you want the most chemical resistant filament, print it in polypropylene.

Price isn't terrible, you can get it for $40/Kg on Amazon:

Amazon.com

If you're just printing if for yourself, use PETG. If it degrades, just print another one. It's cheap!

does anyone have a stl file they know works for a curtis action?
