Supports required for the pegs on the back. I printed at 0.4mm layer height.
Print with 3 shells and at least 30% infill, or the block on the back might crack while pushing into an empty insert.
HSW Soda Can Holder is an old and inefficient model. The new Cup Holder models use much less support material and less material overall. Supports still required. The 80H 70R model is the closest to the original design, meant for soda cans.
New models have not been extensively tested for weight. It's at least safe for a tall glass of water.
