Móc treo chìa khóa từ cuộn spool Prusa

If you want you can print the whole spool and not just the half.  Then just hang it where you want! I recommend just the half because there will need to be alot of supports and you could break it when you take them off.  If you are using pla then do 15-50% infill and if you are using tpu or petg then i recommend 60-90% infill.
