This holds 4 Wiha precision screwdrivers together, so they don't roll away and escape. The holes are sized so they grip securely, but the screwdrivers pull out with minimal force.

Here are the hole sizes, and the screwdrivers I use them for (any others would work, as long as they have the same shaft diameter):

• One 4mm hole, fits philips #1
• Two 3mm holes, fits philips #0 and 3mm slotted
• One 2mm hole, fits 2mm slotted

Holes are specified slightly oversized (+0.25mm), as that's what I found gave the optimal grip. You can scale the model up/down slightly (+/- 2% perhaps?) to change how firmly it holds.

I printed mine with PETG and 0.30mm draft defaults (plus a brim to make it stick). I imagine other settings/filaments would work fine.

I can add additional variations-- just leave a comment if you want more!
