conveyer bet, moving belt

this is a conveyer belt, designed in solidworks and printed using Creality ender-3, 3D printer.

this belt is available to work using stepper motor (NEMA17 Stepper Motor)

it should be noted that this conveyer belt has a variable length, and the user can extend (increase the length) of the belt by increase the number of slots and connectors. minimum number for the slots is 38 and for the connectors is 8. these two numbers will lead to the belt in its shortest length, increasing these numbers will increase its length.

this design has the following 3D printed parts:
1- slot, minimum of 38 parts needed, NO support required.
2- connector , minimum of 8 parts, No support needed, increase the number of prints of this part to increase the length of the belt.
3- carrier left side, only one part needed, which carry the first pully from the left side.
4- carrier right side, only one part needed, which carry the first pully from the right side.
5- stepper holder, one part needed, which carry the second pully from one side and holds the stepper motor in its place.
6- DC motor holder, only one part, this one carry the second pully from the other side
7- Dc motor carrier, optional , this part is optional that carrier the DC motor.
8- bearing cover, 4 parts , used to cover the ballbearing.
9- coaster cover, 4 parts, that covers the ballbearings of the coasters.
10- coaster, 2 parts, that holds the first pully and tension it using the four screws.
11- support, one part minimum, used to decrease the curvature of the upper side of the belt. if the belt built longer, another support part needed.
12- pully, two pullies are needed, NO support needed.
13- screw head, four parts, to ease the use of the four screws that tension the belt.

it requires bolts, nuts, and ballbearings :

• M2*50mm, bolts for the slots, the number of them depends on the length of the belt, but with minimum of 40 pieces.

• 4mm diameter shafts, quantity (one for each pully), each of length 20 CM.

• M3*25 mm for the structure, quantity 54, (for minimum length of the belt)

• M6*124 mm for the tensioner, quantity 4, two for each side. with four nuts, with hex head.

• 684zz 2z flanged ballbearings quantity 8 , 4 bearing for each pully.

• 5-4 mm coupler for the stepper motor.

all of the parts requires NO support.
