CMMG Bolt Case

thingiverse

General Description: This is a case that will hold the CMMG 22LR conversion bolt for an AR-15. It also doubles as a regular Bolt carrier group case as well. The Bolt is almost a perfect fit and very little wiggle room. If you want more clearances for the bolt you can scale it up 1-2% but you have to do this to the lid as well or they wont fit right. Printing: The print for both the lid and the base will take roughly around 16 Hrs. at a resolution of 0.2mm. No supports are needed. I recommend a wall thickness of 1.5mm - 2mm. The base is designed as a solid part. The infill i used is 20%. MAKE SURE IT STICKS TO THE BED WELL. This is a long skinny part so it can warp if easy if it isn't stuck down good. I have a glass bed and use regular glue sticks. This Box was designed in Fusion 360, if you have any other improvements send me a comment.
