Detroit Terminal Railway coasters.
Being a railfan I decided to tried my hand at making railroad coasters in Fusion 360. The print profiles worked for me but they might not be the best so feel free to tweak them. These are 3mm thick, 89 mm in square. I printed them face down on the textured plate.
I attached cork on the back side of the coasters to keep them from sliding around on the table. I have put the link to them on Amazon below . You may have copy and paste the link.
If you use a different cork backing you may have to adjust the height of the coaster holder.
Because these Self-Adhesive Cork Squares are pretty much the same size as the coasters I found that by using my paper cutter and trimming off about 1/8" from two opposite sides made it much easier to attach them. https://a.co/d/3ph1R9K
I would greatly appreciate it if you could take a moment and rate my models and profiles, Thanks
