Custom 3D Knob Replacement For Electric Fencer When Matt Steffen’s family member lost the control knob of his Solar Pak 6 electric fencer, he ran into an unexpected problem. “He couldn’t tell whether the fencer was on or off,” says Steffen, owner of an agriculture design business. “He called me to see if I could help and provide a practical solution.” Using his expertise in 3D design and printing, Steffen created a replacement knob with a small set screw to securely attach it to the fencer and an arrow to clearly indicate the on or off status. “This customization ensured the knob was not only functional but also user-friendly,” Steffen says. The process involved drawing up the model in specialized 3D software and printing several versions to test fit and functionality. While printing proceeded smoothly, the spooled plastic filament required 12 hours of drying to remove moisture before printing. The entire project was cost-effective, with material expenses around $2. “He was thrilled with the result and has been using the new knob ever since,” Steffen says. “This experience highlights how accessible technology can provide a handy way to fix something small and demonstrates the value of practical design in everyday agriculture.” Contact: FARM SHOW Followup, Matthew Steffen, 228 N. 12th St., Lincoln, Neb. 68508 (ph 402-640-8041; n3strategic@gmail.com).
