YETI Rambler Colster 12oz Keystone Inspired Extended Caps 16oz and OEM sizes too

thingiverse

I printed several custom can topper files found on Thingiverse, but none fit the Coors/Keystone taller can. A long story short, I decided to create my own design using rulers, calipers, paper, and a pencil to get precise measurements. My design includes: - The cap is 34mm tall, with a 1mm lip, which provides a secure fit. - The thread pitch is roughly 4mm, with a diameter of 72mm. However, I discovered that the thread depth needed to be increased, so I used ANSI Metric M75x4 instead, which shifted the thread profile by 3mm and created overhangs on the threads. To address this issue, I added a supporting curve to one side of the thread to help with printing. The support is based on the top can flange as the first layer printed (180 opposite default position). I also made some adjustments to the print settings: - A 2-layer shell was used with a .5 nozzle and .3 layer height at 25% infill. - I didn't need supports for my PETG prints, which ensured good bonding between layers. The design includes an OEM size cap (23mm) and a Keystone 16oz cap (58mm). The OEM square lip shelf is awkwardly in the way when taking a drink, so I may never use the original caps again. I also created a simplified version of the yeti_cap_keystone12v4 drawing with the file yeti_cap_tall12. It's optimized for printing threads down/first/default and has improved thread quality and lip angle. The design includes three cap sizes: yeti_cap_tall12, yeti_cap_tall16, and yeti_cap_OEM.
