I took some time to come up with a nice-looking holster design for a Slingshot that I love, the EVO Slingshot and Uniphoxx Enzo Slingshot.
Handmade from Rustic brown Crazy Horse leather 4-5 OZ 
Leather Type (Rustic Brown): Laredo Crazy Horse Rustic Veg Tanned Leather. Crazy Horse leather is full of character and they are ideal for achieving an aged, rustic look.  
This leather has a unique rustic pull-up that adds beautiful depth to the leather and makes for an amazing patina as it ages. 
The leather is dyed completely through and has a nice soft flesh side. This leather has a great feel in the hand.
This holster will fit perfectly many Slingshots:
- The EVO Slingshot
- The Hedgerow H.H. by Matt Reading Slingshot
- The panther by Joerg Sprave slingshot
- The Uniphoxx Enzo slingshot
✔ It is small, elegant, and can be attached to a belt. It will fit a belt up to 1.5 inches.
✔ It has two snap buttons to accommodate many slingshots
✔ Premium full-grain veg-tanned CRAZY HORSE RUSTIC leather
✔ Hand saddle stitched with military parachute grade thread
✔ Very solid construction, this will stay with you for a lifetime
✔ This is a great gift and it can put a smile on faces
✔ You will love it because it's compact and look nice. 
✔ Handmade in Canada, Quebec
Note: Slingshot is not included
