Summary

For only 5€ and a spool of filament, you can build yourself a serious DREMEL Drill Press and be VERY proud at the result!

Using cheap bearings this is a very easy and FUN build of a very robust and precise lineair guidance system.

Design features:

• Easy and fast DREMEL placement.
• Almost 10cm Drill clearance.
• Ajustable Hight
• Lockknob to fixate lever.
• Big stable and sturdy ground plate. (Need a 25cm X 25cm printbed. Working on a smaler version witch will fit on a 22cm x 22cm Ender3)
• Easy to assemble, no special tools required.
• Simple but very accurate vertical guidance with bearings. 100% without play.

UPDATE 1-5-2020: On VERY populair demand I finally find some time to design a base witch should be printable on a 220 x 220.
UPDATE: Added holder for Dremel 3000

!! Included universal base with STEP file so you can design your own Drill Holder!

BOQ:

Tube or Pipe

For the steel pipe I used 22mm steel pipe 1.4mm thick. It's very cheap and common so easy to find in your local DIY shop. Here they use it for central heating.

Pipe Nominal Bore 1/2 inch (DN 15 mm), Outside Diameter 21.34 mm should also work!

Cut 2 pieces:
35cm and 25cm.

3D Printed Parts

I use regular PLA. It's very stiff and strong. Make sure you print with minimum of 5 top, bottom, outer and inner layers.

Assembly instructions follow beneath. Have fun with this build and please give me likes as appreciation for my work.

One last tip. Revisit this page and download the latest versions just before you start printing. Maybe there are chances in the design.

Requierments

Make sure you have al the parts ready and printed before the fun start!

Start by mounting the 35cm tube into the base

Use 3 x M5 X 30 Bolts..

Do NOT tighten the bolds to much. No need for that.

Step 2

Assemble the Vertical guide with the bearings. Please note the gaps for nuts...

Do not tighten the yellow arrow bolts yet. You can use them to tighten the bearing grip on the steel pipe. The blue arrow point to a slot for a M5 nut. Not in the picture.

Assemble the short pipe in the DREMEL holder.

Insert the DREMEL mount pipe in to the vertical guide. You need a bit of force for that. Glue the top cap with cable guid in place.

Assemble the lever with some glue and montage it onto the press. Note that with the big knob you can fixate the Dremel and adjust the motion resistance so the Dremel will stay in place. **Note that the Socket Hex bolt is self tapping.** Don't over tighten it!

Assemble the leve

Almost done. Mount the DREMEL. Unscrew the cap, slide in the DREMEL and put the cap back in place. Tight it firmly. Start drilling...
