Gridfinity for IKEA HELMER
IKEA's HELMER drawer unit with its six metal drawers is a classic in workshops and craft corners. It comes in two versions with different drawers – here are inner dimensions, grid and split for both.
| Version | Inner size (W × D × H) | Units | Padding | Max. bin height | Parts on Bambu P1S / A1 mini | |
|---|---|---|---|---|---|---|
| HELMER 28 × 65 cm (current) | 220 × 370 mm | 5 × 8 | width 4.5 mm each, depth 16.5 mm each | measure yourself | 2 / 6 | Open |
| HELMER 28 × 69 cm (older version) | 231 × 388 mm | 5 × 9 | width 10 mm each, depth 4.5 mm each | measure yourself | 2 / 6 | Open |
Default clearance 0.5 mm per side. Height in 7 mm units, with the “Lattice” baseplate, stacking lip and 0.5 mm air, without a lid. Parts = baseplate split for the print bed.
Which HELMER do you have?
The current HELMER measures 28 × 65 cm, older units 28 × 69 cm. Their drawers differ: the current one takes 5 × 8 units, the older one 5 × 9. If unsure, measure the drawer inside at the bottom.
Shallow drawers, little height
HELMER drawers are shallow. The usable height depends on how far the drawer above reaches down – measure it yourself and enter it in the planner. Gridmint then warns about bins that are too tall and offers to shorten them. Shallow bins with compartments are ideal for small parts, pens and bits.
Measure before printing: width and depth inside at the bottom, height from the bottom to the underside of whatever sits above when closed. If your numbers differ, enter them in the planner – Gridmint recalculates everything.
Few parts to print
The drawers are narrow enough that the baseplate is just two parts on a Bambu Lab P1S or X1. On the A1 mini it becomes six, joined with dovetail puzzle connectors.
