Step 1 - Story

PET MINI (Personal Electric Transport) was developed based on the growing importance of creating participatory approaches to design.

By using the potential of Open Design we can easily prototype and distribute design's at a global scale while promoting local manufacturing and problem solving.

We were grateful to get the recycled plastic PP sheet's from Precious Plastic HQ for the first prototypes, they were machined by a CNC router to obtain the skateboard deck. Mechanical parts were 3D printed to speed up prototyping phase, as the parts were manufactured at a local Fab Lab, VIVALab, so it can easily be replicated at any of the 2,000 Fab Lab's from the global network.

Step 2 - Bill Of Materials (BOM)

There is a whole world around DIY electric skateboards, different specs and consequently several different parts you can choose from. The parts we used allow a top speed of 35 km/h and a range of 36km:

1x 10s BESTECH bms 60a Battery Pack 12s2p (10s3p)
1x BUNDLE HTD 5M 53 teeth Belt 265mm
1x Electric Skateboard Speed Controller Open Source VESC
1x Eskating PRO motors 6374 190Kv
2x Caliber II Trucks 50° 10″
4x Kegel 80mm Wheels
8x ABEC 608
1x 2.4GHz remote
1x 16T Motor Pulley (8mm or 10mm)
1x 3D printed Wheel gear Pulley and Motor Mount
1x Skateboard Hardware Set - 1"
2x 1/2" Rubber Riser Pads
1x 1m of 1mm Rubber Window insulation

Step 3 - Sheet Press, 3D Printing & CNC

Start by making your 20mm sheet using the sheetpress.

0.3mm layer hight

👉 Motor Mount:
<45% Infill
0.2mm layer hight

👉Wheel Gear Pulley:
PC-ABS or Carbon Fiber
<45% Infill
0.2mm layer hight

3D CNC Milling 20mm Plastic Sheet using the 3d model of the deck parameters will depend on the available CNC at your local Fab Lab or Makerspace.

Step 4 - Electronics

We share with you a comprehensive tutorial to program your electronics and to assemble your electronics

Step 5 - Have Fun!!!

After Assembling all the different parts, programming your electronics and adding the rubber insulation to the Electronics case you are ready to test your e-skate.

Ride Safe and Have Fun! 🛹♻
