This is a drill press that can be easily customized for different tools just by replacing a couple of parts. The included supports hold a Dremel 3000: if you have a different rotary tool, or maybe you want to use your soldering iron to press threaded inserts, you just need a different tool older to screw in to the base of the support column.

It uses aluminum tubes (20mm OD / 18mm ID), one 30 cm in length, the other one 20 cm in length. There are 8 623 ball bearings: 6 for the tool column, 2 for the lever.

I've used a mix of M3 screws and some threaded inserts to assemble it:

4x M3x8 flat head screws + threaded inserts for the plate
3x M3x12 socket head screws + washers + nuts to secure the back column to the base
2x M3x12 button head screws + washers + nuts to mount the front ball bearings, left side (I used 1 washer behind each bearing to avoid any play)
2x M3x12 button head screws + washers + nuts to mount the front ball bearings, right side:
2x M3x18 socket head screws + washers + nuts to mount the back ball bearings (I used 2 washers around each ball bearing). Suggestion: tighten the screws of the 6 ball bearings only after mounting all of them; tighten the backside screws until the sliding column works smoothly without play.
1x M3x14 socket head screws + washer + nut to secure the front column support to the back column
2x M3x8 + 1x M3x16 socket head screws + washers + nuts to secure the bottom of the tool support. The longest screw also keeps the spring in place:
1x M3x6 socket head screw + nut to tighthen the small ring at the top of the tool column
4x M3x6 socket head screws + threaded inserts to mount the bottom Dremel holder to the front column support
1x M3x10 socket head screw + threaded insert to mount the top Dremel support to the column
1x M3x4 button head screw (but a M3x6 SHCS is fine as well) + threaded insert to fix the spring at the top
1x M3x8 + 1x M3x6 button head screws + threaded inserts to mount the two halves of the lever handle. The handle contains a ball bearing like those used around the main column.
1x M3x25 socket head screw + threaded insert to mount the lever to the column
2x M3x12 flat head screws + threaded inserts to mount the lever ball bearing to the tool support column
2x M3x4 socket head screws + nuts to mount the ball bearing guide to the lever

I've used minimal supports in this print.

what are these black parts in the middle? it looks like there should be a bigger washer but in your description and materials list is none.

@Wiz_78

there's a ball bearing inside the 2 pieces of the lever

@Deepflash

Replying to @Wiz_78 :

you mean a 623zz? you should mention that in the instructions

@Wiz_78

Replying to @Deepflash :

yes. I've edited the description as well.

@Deepflash

man you need to harmonize the screws to have much less different ones :)

The designer has replied

@Wiz_78

you're probably right... but I've got a box full of them, I need to use them somehow... :D You can use different ones in most places, though, if you don't care about them being just the right size

@Deepflash

Replying to @Wiz_78 :

makes it easier to get into the project if you have less different ones.. the hurdle is simply smaller :)

@pixelkarma

screw harmony.

It took me a minute to figure out what was going on with the instructions, but overall very happy with how it turned out. Getting the washers and ball bearings assembled will likely fill up up your swear jar, but it came together nicely and does what it says it does. 9/10.

perfect I just added reinforcement to avoid forcing the axes

There is some freedom in the system, making precise drilling difficult.

Printed nicely in PLA. Assembly is a bit of a faff, but ultimately okay, good practice for setting heated inserts :D Fits the 3000 much better than the OEM drill press from Dremel. Getting the bearings aligned to make sure it travels straight without rotating is quite a lot of work, for me it constantly wanted to rotate off-axis. Eventually I got it by fiddling with all the screw tensions for half an evening.
