I've decided to share my remix of the Modular & Stackable Golf Ball Display Stand + Mount by dusti

This stand holds 5 balls per row and you just need to print more of the stackable bases to increase the height. There's a separate top panel that's intended to print upside down to give a nicer bed finish, and there's a left and right side wall mount sized for typical #8 sized drywall anchor bolts. CAD is included so feel free to remix as needed. 

Print Settings:

• Standard PLA is more than fine. I used 3 Walls and 20% Gyroid infill for the shelf sections
• Wall Mount brackets I used 4 walls and 30% Gyroid infill. 

Modifications I made:

• Made the display 5 balls wide to maximize the footprint on the A1/P1 bed size. This model as it is won't fit on the mini.
• Added small m2 screw holes to the top panel to make it more removable and modular to add more base sections as needed.
• Cut out the holes on the top ball holders to allow it to print upside down with no supports. 
• Added various chamfers and fillets to clean up the design to my preferences
• Reduced the wall bracket size to slim down the footprint.
