You will need lots of "magic locks" (Keyhole lock Burg-Wächter ME/2 or "Aliexpress stealth lock") and 30mm strap as well as some 30mm buckles - see images. Print at least the back joint, the main buckle and lid and two front couplers plus lids. First get one piece of strap fitting around the waist, plus some extra length for the buckles. Thread the back coupler to this strap and place the two front couplers left and right to it. Attach buckles to both ends of the waist strap, place the strap around the waist and adjust the two buckles so that the strap fits tightly and the buckles can be placed into the main buckle. Don't forget to place the front couplers left and right of the main buckle. Prepare another piece of strap running from one front coupler through the crotch to the back joint and back to the second front coupler. Run the ends of the strap through the corresponding front coupler and attach a buckle to each end. Fit the buckles into the front couplers. Now you might bring the main and front coupler lids into place and lock each of them with a stealth lock. Basic setup done. For security, you can run the crotch straps through the base of Mr. K (https://www.thingiverse.com/thing:4382929) to safely hold it in place. Secure the rear port. Next, thread the straps on through the tunneled base of The Pear Of Anguish (https://www.thingiverse.com/thing:4376705), which allows for securing the front port. The base of Mr. I (https://www.thingiverse.com/thing:4378279) is designed to be attached to the crotch strap. Make your choices and play safe, sane, and consensually at your own risk.
