Designed a hideaway bolt keychain. Have yet to print it, in anticipation of the threads not fitting, the bolt head has been scaled to 101%. Threads are a 5mm triangle that was revolved around the 75mm cylinder. Worked the top and bottom of the bolt body to clean up the start and end of the threads.
Thanks for sharing; nice work! Curious what exactly is a hideaway keychain? Is it one of these Swiss Army knife like devices with keys that fold in/out?
The bolt is hollow, so you can store pills, money, or whatever in it. The bolt head threads securely on the bolt and when attached it isn’t apparent that it’s hollow. It can be scaled appropriately to be a cool little keychain.
