TO-220/TO-247 Jack-Screw Heatsink Clamp Bridge
A 62 x 23 x 12 mm U-shaped bridge that clamps a TO-220 or TO-247 transistor or regulator flat against a heatsink. Two M3 screws (3.4 mm clearance holes, 46 mm apart) go through the feet into the heatsink. An M3 jack screw in a 4.0 mm heat-set insert at the top of the bridge presses down on the package, so you don't have to drill and tap through the tab or use an insulating bushing. The opening under the bridge is 18 mm wide x 12 mm high.
Acrylic Panel Enclosure Corner Post
A corner post for building custom project boxes out of 3 mm acrylic, plywood or scrap FR4: the side panels slide into two 3.3 mm grooves (3 mm stock + 0.3 mm clearance, 19 mm engagement) and the base and lid screw into M3 brass heat-set inserts at each end (4.0 mm bore, 6 mm deep). Post is 50 mm tall with 30 mm legs, 9 mm thick; print four and cut panels to whatever size your PSU, amp or controller board needs.
