Rotary Tool Accessory Organizer for Skadis – 4 Modules, M3 T-Nut

A compact organizer for a whole rotary tool accessory collection on an IKEA Skadis pegboard (normal orientation, vertical slots). I designed it for my Parkside PFBS 12 C6 kit plus an extra Parkside accessory set, but it works with any accessories on standard 3.2 mm (1/8") shanks – Dremel, Proxxon, Parkside, generic 100+ piece kits.

Bits stand on stepped tiers (front rows lower, back rows higher), so you can see and grab every one. Hole spacing depends on the head size, which keeps the whole set in about 34 × 19 cm of board space.

MODULES (each 156 mm wide)

- A – drills, small and medium bits (156 × 91 × 54 mm): 18 drill holes in 5 sizes, size embossed on the front (up to 1 / 1,5 / 2 / 2,5 / 3,2 mm – put each drill in the smallest hole it fits), 38 holes for heads up to 9 mm (burrs, engravers, small stones, mandrels), 26 holes for heads up to 15 mm (stones, rubber points, sanding drums).

- B – large heads up to 25 mm (156 × 71 × 44 mm): 14 holes for wheel brushes, felt and rubber wheels, big stones.

- C – largest heads up to 33 mm (156 × 58 × 39 mm): 7 holes for flap wheels and big grinding wheels.

- D – loose parts (156 × 88 × 90 mm): 6 wells for ~17 mm discs, 4 wells for ~32 mm discs (each well has a hole in the bottom – push the stack up with a finger from below), 7 pegs for sanding bands (4× 12.7 mm, 1× 9.5 mm, 2× 6.4 mm, 5 bands each), 2 pockets for collets, wrench and dressing stone.

Shank holes are 3.5 mm in the model. Vertical holes print slightly smaller, so 3.17 mm shanks slide in without wobbling.

MOUNTING

- Hardware: 2× printed M3 T-nut + 2× M3x16 socket head screw per module (8 of each in total).

- The screws sit in the back plate above the highest tier, 120 mm apart, in one row of slots. Alignment guides on the back keep each module straight.

- Mount the empty module first, then fill it – the back rows hide the screw heads.

- My layout on a 36 × 56 cm board: B and C in one row (centres 160 mm apart), A and D above them with the screws 100 mm higher and shifted 20 mm to the right. The modules are independent, so any layout works as long as the screws land on slots.

PRINTING

- Print each module standing, as in the files. No supports, no brim. The alignment guides have a 45° chamfer underneath.

- 0.2 mm layers, 2 perimeters, Lightning infill 10% (saved in the 3MF files). PLA is fine – nothing here carries load or gets hot.

- About 250 g of filament for all four (A ≈ 78 g, B ≈ 50 g, C ≈ 40 g, D ≈ 81 g).

- 3MF projects: plate 1 = A + C, plate 2 = B + D, each fits a 250 × 220 mm bed.
