8 notes pipe organ
Description
Wow this has been a long project! In September I decided I was going to make a small pipe organ for my two nieces for Christmass. By chance our familly reunion was on the 30th of December, and I finally made it in time. For this project, you will need to buy the following parts: -Bamboo skewers -M3 X 4mm button head cap screw (16) -M3 X 18mm sochet head cap screws (7) -M3 X 40mm socket head cap screws (5) -0.8 X 11 X 21 mm spring (8) -1/8 X 8 1/4 in brass rod (1) -GDSTIME Blower 9733 with cylindrical nozzle and power control(1) Here are some links for these items: https://www.amazon.ca/Metal-Compression-Spring-Silver-0-8x11x21mm/dp/B07D76QQV6?pd_rd_w=thxKA&content-id=amzn1.sym.5227a24c-8e93-45c4-815c-d02346cda8bb&pf_rd_p=5227a24c-8e93-45c4-815c-d02346cda8bb&pf_rd_r=8BGJ4FPV60EPZKNKPPY3&pd_rd_wg=7clOB&pd_rd_r=7a865982-00bd-4c25-bf73-655352b9b977&pd_rd_i=B07D76QQV6&psc=1&ref_=pd_bap_d_grid_rp_0_1_ec_pd_rhf_ee_s_rp_c_d_sccl_2_2_t https://www.amazon.ca/dp/B0BZRQT6M6?psc=1&ref=ppx_yo2ov_dt_b_product_details https://3dprintingcanada.com/collections/parts-nuts-bolts-bolts/products/stainless-steel-metric-thread-button-head-cap-screw-10-packs?variant=39532754042949 https://3dprintingcanada.com/collections/parts-nuts-bolts-bolts/products/stainless-steel-metric-thread-socket-head-cap-screw-10-packs?variant=39532745326661 https://3dprintingcanada.com/collections/parts-nuts-bolts-bolts/products/stainless-steel-metric-thread-socket-head-cap-screw-10-packs?variant=39532745457733 Optional: a book of simple songs https://www.amazon.ca/dp/B0B1CQ2R1T?psc=1&ref=ppx_yo2ov_dt_b_product_details The pipes were printed upside down with a raft. The longer pipes would not stick well enough to the bed without the raft. But for smaller ones a brim was enough. I even joined two pipes together in cad with small tabs so they could support each other during printing operations (not included in the files). I wanted my nieces to be able to read music with the Chroma-Notes code system so I bought 8 different colors of filaments. Some are PLA and other PETG. The file colors.doc contains the filaments I used. Of course you could print everything in the same color and material though I am not sure if the valve would flex enough if made with PLA. I used PETG for the valve for its longer elongation at break. Here are the possible improvements that could be made: -The recesses for the spring are too shallow -The distance from the lower wind chest to the valve is too far so the spring are merely compressed and air was leaking. I had to stretch the springs and the action of the keys became too hard. Instructions: -The tapped holes are undersized so you will need to drill and tap them. -The holes for the bamboo skewer pushing rod are undersized so I slowy drilled them bigger until the skewers fit properly. -The pipe are longer than necessary and need to be adjusted with a tuner so the notes are the right frequencies. These are closed pipe so you will need to glue the plugs at the end of each pipe. Make sure tu use the same air pressure when tuning pipes.

This is not common in pipe organs but worked for me.
