Glassware draining rack

Draining rack for laboratory glassware. Model inspired by an ISOLAB draining rack (https://isolab.de/en-us/cleaning-safety-protection-sterilization/drainingracks). It consists of a 4-part backplate, 2-part funnel and individual pegs, all printable on a 256 × 256 mm plate. It can fit up to 30 drying rack pegs (angled 40° upwards) in 6 rows with 5 pegs in each row. The upper 2 rows are spaced further apart and the bottom 4 are spaced closer. The water funnel area is angled 0.5° downwards (to the right) and 2° upwards (in the front), such that the water is channeled to the back right corner.
