This is a Coaster Cover inspired by @Tripwire_586192‘s design made to fit @H3RBSKI's stratagem coaster set. I completely remodeled this in Fusion 360 which is why I'm posting it as an original design and not a remix.

The issues I had with the original  design were the sharp corners causing excessive warping even with a brim and I found the 10mm thick top was excessive and used too much filament.

CHANGES:

• Filleted outer corners and filleted inner corners and edges to improve bed adhesion and overall fit with H3RBSKI's 5-coaster holder. 
• Reduced the thickness of the roof from 10mm to 2.5mm making the overall model height closer to the actual height of the coaster holder and reducing filament use. 
• Logo is now in the same plane as the lid to eliminate the use of supports or bridging when printing it. This has the added benefit of being more consistent with the design of the coasters. 

I printed this using my Bambu Labs A1 mini with AMS Lite
