Khuôn đổ nến (Candle Mold)

It is a candle mold I tried back in the days. It needs to be sealed to work !!!!!! wax is very slippery and finds every little hole....

It needs to be put tightly together with zip-ties or velcro or a lot of rubber bands - so print 100% infill

It needs to be sealed - make thin seals with some rubber glove cut outs around external side edges and thin strip around bottom also.
