Had the parts printed by someone else as my printer always sucked at PETG. It went together well but the hotend can move around alot in the finished and assembled parts. like a couple mm in every direction. all printed parts and bolts fit together perfectly, just the heatsink can move alot. Is this intended or should i shim it with some tape. If so any heat resistant recommendations?
