Dremel 4000 Adjustable Stand Holder

thingiverse

This is an adjustable vertical stand that mates with the Dremel 4000 stand by pogromcajerzyn. You turn the upper knob to raise and lower the carriage, and lock the height with a set screw. I used a standard 5/16"-18 threaded rod* and some 1/2" extruded steel rod* I had laying around for the guide rails, 2x standard skate bearings, and 6x 5/16"-18 nuts from Everbuilt, as well as 5x 5/16"-18 x 1.5" hex bolts. *Size your threaded rod and guide rails based on your own needs. Just make sure your threaded rod is about 2 inches longer than your guide rails. I cut my guide rails to 15", and threaded rod to 17". The carriage top and bottom mount to the threaded rod by sandwiching the bearing between two nuts, passing the threaded rod through the bearing, and press-fitting the bearing into the carriage top and bottom. Two nuts are press-fit into the carriage body, and the threaded rod is threaded through them. I secured my Dremel 4000 into the stand by pogromcajerzyn using some M4 machine screws/nuts, then secured it to the carriage body with the 5/16" hex bolts. Note I used my angle grinder to cut channels into the hex head for easier tightening, though you may not need to. I used some 90° 3/4" brackets to attach two pieces of 3/4" MDF, taking care to secure the two pieces of wood as close to normal as possible. I used a framing square to position my mounting holes for the carriage top and bottom, making sure to align them as vertically as possible. Finally, I painted the knobs with some glossy candy apple red plastic primer/paint. I press-fitted a 5/16" nut into the carriage top set screw hole, trimmed down a set screw** then glued the knobs to the threaded rod and set screw with some CA superglue. **The set screw stuck out too far and interfered with the dremel at the upper end of the carriage's travel range. The best method I've found for cutting down screws is the following: Thread two nuts all the way onto the hex bolt, stick them into a vice, and cut them off with an angle grinder, taking care not to nick the threads up-screw from the cut. When you're done, slowly remove the two nuts from the screw. As they come off, they'll re-align the screw threads at the cut-point.
