Mounts an enclosed supply - Mean Well LRS-50 to RSP-500, the slim UHP-200 and UHP-350, and the LDO LCP300 - on its own bottom-hole pattern: snap onto DIN rail, bolt to 2020 extrusion, fit end brackets, or hang a UHP upright on a 1515 extrusion. Screw length is checked against the PSU depth limit.
A mount for enclosed power supplies, built from each unit's real bottom-hole pattern - no guessed dimensions. Plate style is a counterbored mounting plate under the PSU that mounts to a DIN rail natively - its default clip-slot interface takes a printable TS35 clip and snaps onto the rail, no adapter - or, set to frame mode, carries outboard slots to bolt onto a 2020 extrusion. Brackets style (offered where the case's side-mount spacing is documented) is a pair of L-profile end brackets that bolt into the same bottom holes at each end. Every screw-length option is checked against the PSU's documented maximum-penetration spec, so you can't pick a screw length that reaches the internal PCB. Just make sure you use the right hardware! Slim ear-slot supplies - the UHP class and the LDO LCP300 - fasten the opposite way - their end-plate ears are open slots, not tapped holes - so their plate carries heat-set inserts pressed in from the plate's underside (opposite the bolt, so pull-out bears on a solid taper shoulder) at the ear pattern, and the screws drop in from above. That plate is thick only where it has to be: a thin web with the inserts in short posts the ears sit on, so the supply rides 7 mm above the rail with an open air gap beneath it and the clip screw heads sit under it. Those ear slots are OPEN - the insert sits under the slot's closed, fully-enclosed end (the most captured position; on the UHP-350 the 2 mm of slot outboard of it is the vendor's, not spare travel), so put a washer under each screw head: a bare M3 head bridges the open mouth. Note Mean Well rates full UHP wattage only when mounted on a large thermally-conductive aluminum plate, so treat a printed mount as a derated/light-duty carrier. For DIN-rail mounting, bolt a printable TS35 clip (PSU-class - dins_clip or th0mpy's BEEFY Din Clips, linked on the page) straight into the plate's default clip slots; no adapter. Upright style (UHP-200 and UHP-350): two identical brackets hang the supply long-axis-up on the outside face of a 1515 extrusion, each bracket carrying that end's two ear inserts and a 13 mm shoe with two M3 slot-nut screws. It is the mount from the Tri-Zero build series, fitted and passed by its owner on 2026-09-16, merged into one body per end. It is an off-label mount: Mean Well documents flat plate mounting only, so the without-plate derating curve applies, the extrusion face must be bare (no panel), the nuts must be drop-in slot nuts, and the mains terminals need a guard you fit yourself.

Designed for FDM and exported at nominal size. Choosing a material changes the slicer advice we show - never the part's dimensions - so keep shrinkage compensation in your slicer's filament profile, where it's measured per spool. Clearance fits come from measured fastener and hardware tables. Snap and lipped parts assume a 0.4 mm nozzle; print 3+ perimeters for strength.
Each configuration has its own page with recorded specifications and a link to the generator. Confirm your hardware revision before printing.
