Multi-Tool Press Conversion Kit from Dremel Press

My brother brought home a broken Dremel Press. However, it still included many high-quality parts, so I decided to convert it into a multi-tool press, which uses a self-centering double-V-jaw custom vice to clamp different tools, from soldering irons to drills.

Printing Notes:

The large vice plates are very structurally important. To prevent bending under load from heavy tools like drills, it is recommended to use 35% triangular infill, and the infill direction must be set correctly, where the parallel lines the triangles form run from left to right, creating strength for torques applied along the up-down axis on the front.

For other parts I used 25% cuboidal infill.

All parts were created out of ABS plastic, with a 5+mm brim, bed adhesive, and 6 wall loops for strength and warp-prevention. I do not recommend brittle plastics like PLA because the press will face heavy forces from rotation with drilling, clamping tools down, and holding heavy tools.

The vice gears have a translucent cover piece. I recommend printing in translucent PLA to be able to see gears. Its function is to prevent hair/skin from getting pinched in gears during operation and prevent dirt buildup, but it can be excluded or printed in normal plastics.

Here are the non-printed parts required:

10x15x4 Bearing (4)

3x8x4 Bearing (2)

3mm stainless steel rod (150mm)

5mm stainless steel rod (75mm recommended, any size though)

The extension arm is a random scrap piece of plastic I own, I believe from a broken bike phone holder. It can be replaced by printing it or finding another plastic arm.

OUTSIDE ELECTRICAL PARTS:

These can all be exchanged for different electrical parts. I chose these because I had accumulated extra from various projects and decided to use them.
