Gridfinity Stand for Anker 621 MagGo Power Bank

PowerPerch — Gridfinity Stand for the Anker 621 MagGo Power Bank (1×3, vertical slot, ~1 mm clearance)
══════════════════════════════════════════════════════════════

A Gridfinity 1×3 dock that holds the Anker 621 Magnetic Power Bank
(MagGo) standing upright on your desk. The bank drops edge-first into
a single slot and stays put — wide MagSafe face on show, ready to grab.
Modelled with ~1 mm clearance all around, so it slides in and lifts
straight back out with zero fight, no rattling.

Drop it into any Gridfinity baseplate and your power bank finally has
a fixed home instead of rolling around a drawer.

■ KEY FEATURES

- ~1 mm clearance all around: easy drop-in, easy lift-out, no rattle
- Chamfered slot edge guides the bank in and softens the opening
- Full Gridfinity 1×3 base — locks into any standard baseplate
- 20 mm deep slot holds it stable while ~31 mm stays exposed to grab
- Prints flat, no supports, no assembly — one single part
- Quick & cheap: ~50 g filament / ~1 h (approx. — see note below)

■ COMPATIBILITY
─────────────────────────────────────────────────────

 (~105.5 × 51 × 11.3 mm), held on its long edge
- The ~1 mm all-round clearance tolerates light cases / cable nubs

■ PRINT PROFILE (Bambu Studio)
─────────────────────────────────────────────────────
Default 0.20 mm Standard profile, completely unchanged except:
- Sparse infill density: 15 %
Everything else (walls, top/bottom, supports off) stays at the preset
defaults. Print base down with the slot facing up — no supports needed,
the slot is a clean upward pocket and the Gridfinity base is self-
supporting. Filament/time above are rough estimates from the model
volume; your slice will be more accurate.

■ USAGE
─────────────────────────────────────────────────────
1. Click the dock into your Gridfinity baseplate (1×3 footprint).
2. Lower the Anker 621 into the slot, long edge first.
3. It seats ~20 mm deep and stands upright, MagSafe face out.
4. Lift it straight up to remove.

■ DESIGN NOTES
─────────────────────────────────────────────────────
The slot is cut at 107 × 14 mm — roughly 1 mm larger than the bank on
every side — which is the sweet spot between "drops in easily" and
"doesn't flop around." A chamfer on the top edge guides it in. Designed
around the standard Gridfinity 1×3 base, so it shares a baseplate with
the rest of your setup. To suit a thicker case, scale the slot width or
widen profile1 by a millimetre or two.
