Full body Turntable, worm gear & spur cog, and final 35 tooth GT2 drive cog

A Custom Built 60cm Scanning Turntable Based on Thingiverse's Thing #729923, I set out to create a precise scanning turntable for capturing full-figure models. To get started, I scavenged an old Mini wheel hub from eBay ($17 USD) and paired it with two sections of 18mm plywood for the base and top table, which cost me about $32. Next, I used 11mm MDF to create the center "pulley" part of the table and its guide, setting me back approximately $20. A reliable DC motor that I had on hand took center stage, while a speed controller sourced from eBay ($4 USD) was linked directly to my 3D printer's power supply. To develop the gear train, I repurposed various cogs available on Thingiverse, modifying them as necessary. One of the perks of this design is its adaptability; simply swap out the final 35-tooth GT2 drive cog for a custom creation. The worm – a single tooth helical gear – plays a crucial role in propelling the turntable's motion. By carving the teeth with a concave shape, I enhanced the gear's efficiency by ensuring maximum contact between teeth. This unique configuration not only enhances stability but also simplifies assembly and maintenance. Securing all moving parts requires some precision work: attach the worm cog to the motor drive shaft, then secure the final 35-tooth gear using washers on a 10mm bolt for optimal levelling. By connecting it directly to the GT2 support, I achieved effortless integration into the overall mechanism. Of course, centering is key; drill holes custom-tailored for individual needs make each component easily adaptable for personal preferences. The turntable boasts two drivetrain options: drive it using a 2-meter piece of GT2 belt stitched together or by substituting an inner rubber tube with some creative problem-solving. What worked perfectly for me included sewing together three distinct materials (a length of exercise latex tied up and an inner rubber tube among them).
