Parts

3x Lasercut Acrylic Sheet, 3mm thick

< p style="text-indent: 2em;">Download the template eps file (see below) and place an order at Ponoko (US/International users) or Formulor (German/European users). Choose a 3mm/0.118 inch acrylic P1 board , the color you like. For my turntable prototype, I chose the material "Acrylic - Black (matte 1 side)". If you can access your own laser cutting machine, or if you want to use For other services, simply import the vector path from your EPS file layer called "Your Design" to your preferred program.

8x pan head screw, M3 x 8mm

•4x lens screw, M3 x 14mm

•4x from lock nut, M3

•4x Washe rs M3, outside 9mm diameter (washer should be suitable for rubber feet. You can also buy rubber feet with washers

•4x female - male support shims,M3 x 15mm

•4x female-female holder gasket, M3 x 35mm (please note: the height of the "mother-female spacer" determines the step The maximum height of the motor, here is 35mm.)

I have also prepared some kits, including the need to build my own turntable All parts - except stepper motors:

Tools

Some Allen keys

Phillips screwdriver

Drilling machine with countersunk head Drilling hole < /p>

Step 2:Prepare acrylic plate

First, you should peel off the protective film from the acrylic plate. It is sometimes helpful to carefully preheat the foil with a blower.

Because we want to use the countersunk screws to fix the "upper plate", we need to prepare the corresponding four internal laser cutting holes.

Step 3:Install the motor on the midplane

will step The motor passes through the intermediate plate. Make sure the hole in the motor matches the correct hole on the plate.Secure the motor with four M3x8mm pan head screws.

Step 4: Add Remote Bolts

Through the 15 mm female-male gasket through the plate. Screw the 35 mm female-female gasket onto them.

< p style="text-indent: 2em;">Please note that the "female-mother gasket" determines the maximum height of the stepper motor, here 35mm. If you want to use a higher stepper motor, you must Choose a higher stand spacer or add an extra female-spacer. For example, you can add 4 additional 30 mm female-male pads to achieve a height of 65 mm.

Step 5: Add a backplane

Flip the construction and lower the bottom plate

Now put the washer into the rubber For the feet, insert the M3x14mm lens screw and secure all parts to the structure.

Step 6: Install Lazy Susan Bearings

Place the bearing on top of the gasket.

Make sure the bearing side and 90mm hole are facing down. Secure with four M3x8mm pan head screws.

Step 7: Fix Drivedog

Place the drive on the motor shaft and tighten the screws.

The drive should protrude approximately 2mm above the bearing.

Step 8:添加上板

Place the top plate on the drivedog.

Flip the structure and place it Holes in the bearing to match the holes in the acrylic plate.

Insert the M3x8mm countersunk head screw (through the through hole) and tighten the nut

Step 9:Final turntable

If everything you do is correct, your turntable should look like the 360° image sequence above. Of course, this sequence is made with a second FluxGarage turntable and a white acrylic plate :)

Step 10: Next: Build the controller

The next step is to make the turntable take effect. We will create a controller based on arduino + easydriver to control the stepper motor And the camera shutter.
