Drill holder, made for your set

Tell us the smallest and the largest drill in your set and the step between sizes, and we cut a block with a row of holes, smallest to largest, each drawn a little over its drill so it drops in, with a bevel round the top. You choose how deep the drills sit and how much plastic is left between them. It prints standing up, with no supports.

What you need to hand

The smallest and the largest drill in your set, off their markings or a calliper.
The step between sizes in the set.
How deep you want the drills to sit.
Your nozzle size and the filament you will print it in.

Your drills

The smallest and the largest drill in your set, and the step between sizes. The largest gets a hole even if the last step does not land on it.

Smallest drill

The smallest drill in your set, measured across the shank with a calliper, or read off its marking.

Largest drill

The largest drill in your set. If it is the same as the smallest, you get a block of one hole.

Step between sizes

How far apart the sizes in your set are: 1 for 3, 4, 5, 6; 0.5 for 3, 3.5, 4. If the last step does not land on the largest, the largest gets a hole anyway.

The block

How deep the drills sit, how much plastic is left between them and the bevel round each hole. If the row is too long for the plate, we say what fits.

How deep each drill sits

How far each drill goes into the block. The rest stands out of the top.

Plastic between holes

How much plastic is left between one hole and the next, and between the outer holes and the edge, at the top. More leaves room for your fingers.

Bevel on the holes

A 45° bevel round the top of every hole, so each drill finds its way in.

The printer it will come off

Set these to the nozzle you will print with and the filament you will use. The nozzle decides whether the walls and the floor come out the way we drew them; the filament only sets the weight estimate.

Nozzle size

The nozzle you will print with. It does not change the model — it decides whether the walls and the floor come out the way we drew them.

Filament

Sets the weight estimate. It does not change the model.

Finer adjustments

Floor under the holes

How thick the block is under the bottom of the holes.

Hole clearance

How much bigger than each drill its hole is drawn. Printed holes come out a little small, so we need at least 0.25 mm; more drops in more easily but leans.
