Topic: Dremel Drill Press V1.0

Not sure where the borderline between prints and projects are. Anyway, spent quite a bit of time this evening modelling myself up a Dremel drill press. Almost everything will be 3d printed, apart from rubber bands/springs and PVC tubing as the vertical frame.

Here are some renders of the completed model:

https://lh5.googleusercontent.com/-WmByMuLJXB8/UOmSLobNlRI/AAAAAAAAA9Q/PNw6QxawfPA/s640/DrillPressInternals.png

Everything is designed to snap together. Here is a wireframe of the pinion/axle setup:

One it all works, and I have all the tolerances sorted out. I'll release the STL's.

Re: Dremel Drill Press V1.0

i'm excited! You're the man. This will be really nice to have around. My university makes it a PITA to use their student equipment, so to have a mini drill press in my dorm makes me much more comfortable to leave my father's workshop and head back to school tongue.  The gears on your Z-lift in the initial photo seems a little poorly suited to plastic (they seem to be metal-sized) but maybe I'm just not imagining well.

Re: Dremel Drill Press V1.0

Depending on what your drilling into, you may want to design it to use a cordless or corded drill instead. Would give you a better chuck and better range of speed.

That's a lot of weight for plastic parts!

Re: Dremel Drill Press V1.0

Some of the smaller cordless drills are in the same weight category, though I guess the torque would be more of a concern. It just comes down to the size of bit your trying to use.

Re: Dremel Drill Press V1.0

Most cordless drills don't have speed switches, or a threaded collar like the dremel. You can buy properl dremel drill presses, but where is the fun in that?

@Tomek I did test print the rack and pinion before I designed the whole drill press. They seem to work just fine.

Re: Dremel Drill Press V1.0

I'm going to be using your design or a close derivative soon. Been making a few PCBs and want a good solution.

Ordered a couple of these:

Looking forward to you releasing your STL files.

Show us picture's when it's done. I could use a drill press myself at home.

Re: Dremel Drill Press V1.0

So got it all printed and working. Only needed to reprint 1 piece so far. Here are some photo's, will add some better ones when I get the DSLR back off my friend.

Nice!!! Caswal, So are you going to design a vice for the baseplate? ... maybe with a crossslide smile

Re: Dremel Drill Press V1.0

Better yet, model a hole in the wheel (if possible, don't know the tolerances) and then make a spindle handle that locks in to the hole to allow you to spin the wheel via the handle.

Not a bad idea, will give it a go. (If I can can get the wheel off again, pretty tight push fit).

I'll get my DSLR and make a proper video tonight talking about it, and take it apart a bit more.

Re: Dremel Drill Press V1.0

Looks great, Are you going to release the STLs?

My drills and motors arrived yesterday.

Got a couple of things I want to adjust before I release the STL's. Things that I fixed with the dremel post print. Give me a day or 2.

Re: Dremel Drill Press V1.0

Still havn't had time to fix these up like I want. So I'll just put the STL's up and list the couple of problems I had. This'll be spread over a couple of posts. As it is a lot of STL files.

Re: Dremel Drill Press V1.0

The Dremel holder has slots in the back of it, to connect it to the rack. I found these got a little misprinted (the overhangs are a little much), and were not quite wide enough so needed to dremel'd a little wider.

The Shim is a little cludge fix, that gets stuck to the back of the main carriage at the top. To keep the 15mm PVC pipe/carriage in alignment.

I would also integrate the Wheel, Wheel Connector Shaft, and Square Connector all as one piece, rather than 3 seperate pieces.

All of the fittings such as the shafts (both square and round) will need a little bit of a sand.

Re: Dremel Drill Press V1.0

The final 2 pieces.

The main carriage also uses an M6 Bolt and Nut to grip onto the 15mm PVC pipe used as the vertical rail/support.

Re: Dremel Drill Press V1.0

Thanks caswal.

Mine will be a bit different but you have saved me a great deal of time, no doubt.

Re: Dremel Drill Press V1.0

Just had mine partly break on a part I feared it might happen on. I had one of the shaft parts (just as it enters the pinion gear) sheer across the grain.
