Dremel 3000 Drill press

thingiverse

Drill press for Dremel 3000 designed specifically for drilling small PCB boards, created in FreeCAD version 0.18. I printed this drill press using PETG with a 30% infill rate (cubic) and a 1.2 mm shell thickness. -------------------------------------------------------------- To print the various components: Endstop - Limit travel by printing two of these units with the flat side facing down, no supports required. Use either brim or skirt to secure the parts during printing. Lever - Mirror this design if you are left-handed! Print the lever with the flat side facing down, no supports needed. Use either brim or skirt for support. Nut - Secure your tool using this nut by printing it with the flat side facing down, no supports required. Use either brim or skirt to secure the part during printing. Return spring mount - Secure the upper part of the return spring by printing this component with the flat side facing down, no supports needed. Use either brim or skirt for support. Slide - This is the sliding part of the tool, featuring holes for M5 bolts that are self-threading. Print it with the tool-side surface facing down, no supports required. Use either brim or skirt to secure the part during printing. Spring - Mitigate some play in your drill press by printing this spring component, starting with a medium stiffness. It fits onto the Slide and should be printed on its side. Use brim and supports for this part. Toolmount - Attach the Slide to this component, which has the bottom surface facing down. The M5 holes will require supports to keep them round during printing. Use either brim or skirt for support. -------------------------------------------------------------- To acquire the necessary components: T-slot aluminum profile 20x20 mm in a length of 200 mm (*1). A footplate of some sort. M5 x 8 mm bolts - you'll need nine pieces. M5 T-slot nuts - five pieces are required, and I recommend printing them with 100% infill for maximum snugness. You can use this design by chipg07: https://www.thingiverse.com/thing:2544883 Return-spring - mine has a diameter of 7 mm, a length of 50 mm, and a wire thickness of 1.0 mm. M6 threaded rod in a length of 45 mm - you'll need one piece. M6 nuts - two pieces are required. M6 washer - an optional but recommended component to keep the lever from bumping into the top endstop. You'll need one piece. *1 The shape of this T-slot profile is critical for snugness, so be sure to use a 20x20 mm design with slots that are chamfered at 6.4 mm and a center hole for M6 threading. *2 I used this design by chipg07: https://www.thingiverse.com/thing:2544883, which is licensed under the Creative Commons - Attribution license (http://creativecommons.org/licenses/by/3.0/).
