I modified the magnet holder for IPSC belt in order to fit the Tek-Lok system. I used the dome part with the thread for the magnet and modelled a Tek-Lok compatible plate around it.
Print dimensions were tested with this belt clip (screws were included; place the rubber spacers between the clip and the print): https://www.amazon.de/dp/B081JLCN1F
No supports required, printed with PETG 0.15mm layer height.
The author remixed this model.
