Rack-A-Tier Style Spool Caddy

I made a smaller version of the Rack-A-Tier style spool caddy for use around my house. The Spool caddy is 9 ¾ inches tall and will hold up to an 1 ½ inch pipe for the axel. I made it so it can snap together for easy storage. It works great when pulling in cable around the house. It takes about 503g per side to print. I'm not sure how much weight it can hold, but its been able to hold a lot. Let me know if their is anything that I can fix/change on the design.
