Barbell Chain Collar

thingiverse

This is a collar for a standard 50mm olympic barbell sleeve to attach caribiners to. I use it to attach chains to the bar in a way that doesn't require multiple sleeves holding them in place. You can secure it to the bar with an M8 bolt. You can buy metal ones of these or print one yourself. If you have any strength issues, just up the infill. Supports were needed to finish the securing hole. The version pictured was made on an Ender 3 with Cura set to extra fast, with 25% infill. For the subsequent versions, I switched to draft for a slower print which meant less work threading the bolt. If this has helped you save some money, feel free to buy me a cup of coffee :) https://www.paypal.com/cgi-bin/webscr?cmd=_donations&business=9WFSPVYAETCYA¤cy_code=GBP&source=url
