Mr. conorokane,
I purchased a set of the Latvian files and worked with my son-in-law and his coworker to print up a set in resin. I have zero experience with 3D printers and/or printing so I relied on my "experts". The pieces printed out very nicely according to my son-in-law. The coworker used an ELEGOO Mars 2 printer to print up the set. When I weighed the 32 pieces on my postal scale they totaled 392 gm. The surface finish was very nice requiring little or no finish sanding. I have yet to paint them and add weights and felt.
For anyone thinking about purchasing the files, I would recommend these files. I live in the USA and the purchase was simple online and the price was less than $11 USD at the current exchange rate. If you have no experience with 3D printing, either find someone who can do them for you or purchase an already printed set. I paid the coworker $55 USD for his time and materials so the total price before painting was $66 USD.
To be totally transparent, I have no connection with Mr. O'kane, and I found the link to purchase the files on this forum.
Your photos are very representative of the finished product after painting. Now I just need a bigger board with at least 2.25 inch squares. Oh well, I needed another woodworking project to add to my list.

The STL files to print your own are $15, or you can buy pre-made sets from various vendors (starting at $70) if you don't have a 3D printer.
